The use of photocatalysts to promote the production molecular hydrogen from water, following so-called water splitting reaction, continues be a promising route for green fuels. basis this photocatalysis is photoexcitation electrons valence band semiconductors their conduction band, which they can transferred chemical reactants, protons in case reduction reaction. mechanism by such process takes place has been studied extensively using titanium oxide, simple material that fulfills most requirements splitting. However, with TiO2 tends highly inefficient; cocatalyst, commonly late transition metal (Au, Pt) nanoparticle form, needs added facilitate H2. widely believed help scavenging excited semiconductor order prevent recombination accompanying hole formed step cancels initial photon absorption and competes photolytic reduction. Here we review analyze argue an alternative explanation, role atomic atoms produced proton on surface instead. First, summarize what known about electronic structure these how levels need line up feasible. Next, current understanding dynamics steps associated photons, de-excitation via electron–hole pair fluorescence decay, transitions lead reduction, contrast those rates required produce hydrogen. section addresses changes introduced addition comparatively evaluating its as either electron scavenger or promoter atoms. A discussion viable mechanisms latter pathway included. Finally, briefly mention other aspects photocatalysis, including possible promotion H2 visible light resonant excitation plasmon Au nanoparticles, single-metal atom catalysts yolk–shell nanostructures, organic molecules. We end brief personal perspective generality concepts Critical Review.

This study reports the synthesis of ten coordination compounds (1-10) derived from ligand bis((3-aminopyridin-2-yl)selanyl)methane (L) and different metal centers (CoII, CuI, CuII, ZnII, AgI). Single crystals complexes were obtained via slow diffusion overlaid solutions L corresponding metal. Their crystalline structures determined by single-crystal X-ray diffraction (SCXRD) further characterized using spectroscopic, spectrometric, voltammetric techniques. Complexes 1-5, 7, 10 evaluated as cocatalysts mesoporous titanium dioxide (m-TiO2) for photocatalytic hydrogen production water photolysis under solar light simulation, triethanolamine (TEOA) sacrificial agent. The results showed that 4, 5, enhanced m-TiO2 activity, achieving evolution rates at least four times higher than standard P25. Among these, photocatalyst m-TiO2-7 (7 = [Cu2(μ-SO4)2L2]) exhibited highest production, reaching approximately 7800 μmol/g over a 6-h experiment-nearly 26 greater pure (300 μmol/g). These findings highlight potential organoselenium development novel materials based on nonprecious metals.
