Spontaneous hydrogen production using gadolinium telluride.

ABSTRACT: Developing materials for controlled hydrogen production through water splitting is one of the most promising ways to meet current energy demand. Here, we demonstrate spontaneous and green production of hydrogen at high evolution rate using gadolinium telluride (GdTe) under ambient conditions. The spent materials can be reused after melting, which regain the original activity of the pristine sample. The phase formation and reusability are supported by the thermodynamics calculations. The theoretical calculation reveals ultralow activation energy for hydrogen production using GdTe caused by charge transfer from Te to Gd. Production of highly pure and instantaneous hydrogen by GdTe could accelerate green and sustainable energy conversion technologies.

Selective electrochemical production of hydrogen peroxide at zigzag edges of exfoliated molybdenum telluride nanoflakes.

Project description:The two-electron reduction of molecular oxygen represents an effective strategy to enable the green, mild and on-demand synthesis of hydrogen peroxide. Its practical viability, however, hinges on the development of advanced electrocatalysts, preferably composed of non-precious elements, to selectively expedite this reaction, particularly in acidic medium. Our study here introduces 2H-MoTe2 for the first time as the efficient non-precious-metal-based electrocatalyst for the electrochemical production of hydrogen peroxide in acids. We show that exfoliated 2H-MoTe2 nanoflakes have high activity (onset overpotential ∼140 mV and large mass activity of 27 A g-1 at 0.4 V versus reversible hydrogen electrode), great selectivity (H2O2 percentage up to 93%) and decent stability in 0.5 M H2SO4. Theoretical simulations evidence that the high activity and selectivity of 2H-MoTe2 arise from the proper binding energies of HOO* and O* at its zigzag edges that jointly favor the two-electron reduction instead of the four-electron reduction of molecular oxygen.

Unbiased spontaneous solar hydrogen production using stable TiO<sub>2</sub>-CuO composite nanofiber photocatalysts.

Project description:We report on the optimization of electrospun TiO2-CuO composite nanofibers as low-cost and stable photocatalysts for visible-light photocatalytic water splitting. The effect of different annealing atmospheres on the crystal structure of the fabricated nanofibers was investigated and correlated to the photocatalytic activity of the material. The presence of CuO resulted in narrowing the bandgap of TiO2 and shifting the absorption edge into the visible region of the light spectrum. The effect of incorporating CuO within TiO2 nanofibers on the crystal structure and composition was also investigated using X-ray diffraction (XRD), electron paramagnetic resonance (EPR), and X-ray photoelectron spectroscopy (XPS) techniques. The fabricated TiO2-CuO composite nanofibers showed 117% enhancement in the amount of hydrogen evolved during the photocatalytic water splitting process compared to pure TiO2. This enhancement was related to the created shallow defect states that facilitate charge transfer from TiO2 to CuO and distinct characteristics of the composite nanofibers, such as the high surface area and directional charge transfer. The study showed that Cu is a promising alternative to noble metals as a catalyst in photocatalytic water splitting, with the advantage of being an Earth abundant element and a relatively cheap material.

Hydrogen Production from Gadolinium-Promoted Yttrium-Zirconium-Supported Ni Catalysts through Dry Methane Reforming.

Project description:Hydrogen production from dry reforming of methane (DRM) not only concerns with green energy but also involves the consumption of two greenhouse gases CH4 and CO2. The lattice oxygen endowing capacity, thermostability, and efficient anchoring of Ni has brought the attention of the DRM community over the yttria-zirconia-supported Ni system (Ni/Y + Zr). Herein, Gd-promoted Ni/Y + Zr is characterized and investigated for hydrogen production through DRM. The H2-TPR → CO2-TPD → H2-TPR cyclic experiment indicates that most of the catalytic active site (Ni) remains present during the DRM reaction over all catalyst systems. Upon Y addition, the tetragonal zirconia-yttrium oxide phase stabilizes the support. Gadolinium promotional addition up to 4 wt % modifies the surface by formation of the cubic zirconium gadolinium oxide phase, limits the size of NiO, and makes reducible NiO moderately interacted species available over the catalyst surface and resists coke deposition. The 5Ni4Gd/Y + Zr catalyst shows about ∼80% yield of hydrogen constantly up to 24 h at 800 °C.

Nickel Cobalt Telluride Nanorods for Sensing the Hydrogen Peroxide in Living Cells.

Project description:In this study, we report about the preparation of nickel cobalt telluride nanorods (NiCoTe NRs) by the hydrothermal method using ascorbic acid and cetyltrimethylammonium bromide as reducing agents. The NiCoTe NRs (NCT 1 NRs) were characterized through use of different methods. The nonlinear optical measurements were carried out using Z-scan techniques. The results give the nonlinear absorption that arises from the combined two photon absorption and free carrier absorption. NCT 1 has an excellent electrocatalytic activity toward hydrogen peroxide with a sensitivity of 3464 μA mM-1 cm-2, a wide linear range of 0.002-1835 μM, and the lower detection limit of 0.02 μM, and the prepared electrode was strong in sensing in vivo H2O2 free from raw 264.7 cells. Therefore, the binary transition metal chalcogenide based nanostructures have promising potential in live cell biosensing applications.

Hydrogen production using cocaine metabolite in microbial electrolysis cells.

Project description:In this study, the effects of cocaine metabolite, benzoylecgonine, commonly found in wastewater on hydrogen production were investigated using microbial electrolysis cells. Benzoylecgonine dissolved in synthetic urine and human urine containing benzoylecgonine were inoculated to evaluate hydrogen production performance in microbial electrolysis cells. Microbial electrolysis cells were inoculated with synthetic urine and human urine containing the cocaine metabolite benzoylecgonine for hydrogen gas production performance. Gas production was observed and measured daily by gas chromatography. GC-MS was used to analyze the compounds found in human urine before and after operation in microbial electrolysis cells. The metabolite's pH values and optical density in microbial electrolysis cells were analyzed spectrophotometrically. Hydrogen gas was successfully produced in microbial electrolysis cells (~ 5.5 mL) at the end of the 24th day in the presence of benzoylecgonine in synthetic urine. Human urine containing benzoylecgonine also generated hydrogen in microbial electrolysis cells. In conclusion, microbial electrolysis cells can be used to remove cocaine metabolites from contaminated wastewater generating hydrogen gas.Supplementary informationThe online version contains supplementary material available at 10.1007/s13205-023-03805-7.

Electrodeless hydrogen production from seawater using femtosecond laser pulses.

Project description:This study presents the first experimental evidence of direct H2 production from seawater without harmful gas emissions (e.g., CO2, Cl2), which uses multiphoton ionization water splitting with a femtosecond pulse laser. According to H2 analysis using a gas chromatograph, the H2 production rate in seawater was 70 μmol h-1, which was approximately 3.3 times more than the ultrapure water case reported in the literature. This positive effect derives from focusing through the cuvette wall and the more significant Kerr effect in seawater. Such ion enhancement was observed in the case of seawater and diluted seawater compared with the ultrapure water case, but excessive salt can lead to ion suppression and adverse effects. These differences in salinity suggest appearances of nonlinear optical effects near the focal point and ionization of metallic elements with low ionization potential and are discussed in relation to results of bubble visualization, gas composition analysis, and pressure measurement in gaseous products.

Electrochemical Reduction of Nitrogen to Ammonia Using Zinc Telluride.

Project description:Electrosynthesis of ammonia (NH3), an important constituent molecule of various commercial fertilizers, is a promising and sustainable alternative strategy compared with the century-old Haber-Bosch process. Herein, zinc telluride (ZnTe) is demonstrated as an efficient electrocatalyst for reducing nitrogen (N2) under ambient conditions to NH3. In this simple chemical strategy, Zn preferentially binds N2 over hydrogen (H2), and Te, by virtue of its superior electronic properties, enhances the electrocatalytic activity of ZnTe. The analysis of the X-ray diffraction data using the Bravais-Friedel-Donnay-Harker (BFDH) theory predicted a crystal geometry with the active electrocatalytic sites predominantly confined to the (111) planes of ZnTe. The preferential binding of nitrogen (N2; adsorption energy = -0.043 eV) over hydrogen (H2, adsorption energy = -0.028 eV) to Zn on the (111) plane of ZnTe is further confirmed by density functional theory. The ZnTe catalyst is observed to be stable in the acidic medium and delivers a very high yield of NH3 (19.85 μg/h-1 mgcat -1) and a Faradaic efficiency of 6.24% at -0.6 V (versus RHE). Additional verification experiments do not reveal the formation of side products (such as NH2-NH2) during N2 reduction by ZnTe. Further, density functional theory calculations strongly predict that the electrocatalytic reduction of N2 to NH3 by ZnTe preferentially occurs via the alternate pathway.

Redirection of metabolism for biological hydrogen production

Project description:Photosynthetic microbes can produce the clean-burning fuel hydrogen using one of nature’s most plentiful resources, sunlight 1,2. Anoxygenic photosynthetic bacteria generate hydrogen and ammonia during a process known as biological nitrogen fixation. This reaction is catalyzed by the enzyme nitrogenase and consumes nitrogen gas, ATP and electrons 3. One bacterium, Rhodopseudomonas palustris, has a remarkable ability to obtain electrons from green plant-derived material 4,5 and to efficiently absorb both high and low intensity light energy to form ATP 6. Manipulating R. palustris or a similar organism to produce hydrogen commercially will require us to identify all its genes that contribute to hydrogen production and to understand how this process is regulated in cells. Here we describe mutant strains in which metabolism is redirected such that hydrogen production is uncoupled from nitrogen fixation. Our data indicate that three different single amino acid changes in the transcriptional regulator NifA each yielded strains that produced hydrogen even in the presence of the repressing nitrogen source ammonium and in the absence of specific inducing metabolic signals. We used the mutants to show that, in addition to nitrogenase genes, 18 genes outside of the nitrogenase gene cluster may contribute to hydrogen production. Some of these genes are likely involved in efficient ATP acquisition and in channeling electrons to nitrogenase for reduction of protons to molecular hydrogen. Our results demonstrate that photosynthetic bacteria can be genetically manipulated for sustained production of pure hydrogen in a variety of cultivation conditions in the absence of oxygen, nitrogen or other gases as long as light and an electron donor are supplied.
