This nanomaterial was subsequently modified by incorporating different loadings (1%, 3% and 5%) of gold nanoparticles (AuNPs) on the surface, previously exfoliated MoS₂ nanosheets, and CeO₂ nanoparticles (CeO₂NPs). These nanomaterials, as well as the different synthesized catalysts, were characterized by electron microscopy (HR-SEM and HR-TEM), XPS, XRD, Raman, Reflectance and BET surface area. HER studies were performed in aqueous solution, under irradiation at different wavelengths (UV-visible), which were selected through the approInternational journal of molecular sciences363https://www.ebi.ac.uk/biostudies/studies/S-EPMC9820641biostudies-literatureBiomimetic Catalysts Based on Au@TiO₂-MoS₂-CeO₂ Composites for the Production of Hydrogen by Water Splitting.PMC9820641Sampayo PDuconge JCotto MFontanez KHernandez LPetrescu FGarcia DDiaz FMorant CMarquez FOrtiz DMachin AfalseBiomimetic Catalysts Based on Au@TiO₂-MoS₂-CeO₂ Composites for the Production of Hydrogen by Water Splitting.The photocatalytic hydrogen evolution reaction (HER) by water splitting has been studied, using catalysts based on crystalline TiO₂ nanowires (TiO₂NWs), which were synthesized by a hydrothermal procedure.
