    Effect of Pd and Cu co-catalyst on the charge carrier trap**, recombination and transfer during photocatalytic hydrogen evolution over WO3–TiO2 heterojunction

    Co-catalysts are well known for improving the charge carrier’s separation and transfer to species in solution, and hence, the photocatalytic hydrogen production. Thus, in this work, the effect of loading Cu an...

    Energetic states in SnO2–TiO2 structures and their impact on interfacial charge transfer process

    In this paper, core(SnO2)@shell(TiO2) structures with different SnO2:TiO2 molar ratios were obtained by direct hydrolysis of titanium isopropoxide on SnO2 nanoparticles, forming a composite that provided a direct...
