Graphitic carbon nitride (g-C3N4) is a novel semiconductor material functioning in the visible region of the solar spectrum. The present study focuses on the modification of g-C3N4 by deposition of a multiphase Ni(OH)2/NiO/Ni co-catalyst to improve H2 production rate from water solutions of various electron donors including triethanolamine (TEOA) and plant biomass components (ethanol and glucose), under visible light (λ = 430 nm). It was found that deposited co-catalyst particles have a “core-shell” structure with metal Ni “core” and Ni(OH)2/NiO “shell”, which promotes both the adsorption of organic sacrificial agents and the spatial separation of charge carriers. The highest H2 evolution rates observed in a TEOA water solution over a 3 wt% Ni(OH)2/NiO/Ni/g-C3N4 sample exceeded 1200 μmol H2 g−1 h−1. With the use of TEOA as a sacrificial agent, the production of H2 without impurities can be achived, while the use of ethanol and glucose led to the evolution such gases as CO2/C2H4 and CO/CO2. The mechanism of formation of various gaseous products is discussed in detail.
