Main Factors

Water-soluble multicomponent photocatalysts highly efficient for H2 generation under visible light are designed in such a way to simultaneously enhance the three main factors of photocatalysis, i.e. visible light absorption, charge separation, and surface catalytic reaction.

Cu2O/TNA/Ti photoanode showed spectral response outperformed Cu2O/Ti and Cu2O/FTO photocathodes. Cu2O/TNA/Ti showed better spectral response than that of TNA/Ti, ascribed to UV-visible light absorption of Cu2O, not to charge separation enhancement.

Robust photocatalytic activity of Ni–Ag–RTiO2 is attributed to the improved visible light absorption and effective charge separation due to intimate contact between Ni and RTiO2via Ag, as evidenced by Ti3+ in Ti 2p XPS and energy dispersive mapping.
