Hydrogen has drawn attention as a next generation clean energy source. In this study, graphitic carbon nitride (g-C₃N₄) particles with excellent visible light absorption and reduction power were deposited on titanium dioxide nanotube arrays (TNTs) with high reactive specific surface area. As a result, the enhancement of photocatalytic activity (water photo-oxidation and hydrogen reduction power) on TNT/g-C₃N₄ under visible light irradiation was confirmed.
