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.

Light Absorption Property

A facile doping method utilizing inexpensive raw materials was proposed to achieve variation in optical bandgap and UV-visible light absorption property of MoS2 nanosheets. Carbon-assistant heating with degreasing cotton has demonstrated the development of carbon-doped MoS2 nanosheets with enhanced rich defects. The results obtained shown that modified MoS2 nanosheets with the lateral width of ~600 nm are exhibited shift of the intensively blue peaks of photo-luminescence (PL) comparing to those MoS2 nanosheets with a lateral dimension of larger than 1 μm. Optical bandgap of the carbon-doped MoS2 nanosheets was found to be broader than that of the pure MoS2 nanosheets and the prepared samples also exhibited a broadband UV-visible light absorption property.

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.
