They were characterized by scanning electron microscope, powder X-ray diffraction, energy dispersive analysis, diffused reflectance spectra, photoluminescence analysis and BET surface area. The surface area of catalyst B is larger than catalyst A confirming its higher reactivity. X-ray reflectance spectroscopy was used to analyze the sulfur contents in feed. Thiophene was used as a model fuel to evaluate the photocatalytic activity of catalysts A and B. Using the Scherrer equation, sharp and intense signals suggesting their higher degrees of crystallinity, with average crystal sizes for ZnO, Bi₂O₃, catalystsScientific reports19391https://www.ebi.ac.uk/biostudies/studies/S-EPMC10632363biostudies-literatureSonochemical synthesis of heterostructured ZnO/Bi₂O₃ for photocatalytic desulfurization.PMC10632363Morshedy ASMohamed GGAbdelaal AMSayed FNEl Naggar AMAMahmoud RMAShehata MRfalseSonochemical synthesis of heterostructured ZnO/Bi₂O₃ for photocatalytic desulfurization.In this study, metal oxides nanoparticles heterogeneous photocatalysts prepared by coprecipitation and ultrasonic techniques were used for diesel desulfurization.
