Abstract	The rates of photocatalytic production of H$_{2}$ by Pt/N-doped TiO$_{2}$ are significantly affected by the hydrolysis temperature applied during the sol–gel process. Production rates increase as the hydrolysis temperature decreases from 40 to 20 °C. The effects of the hydrolysis temperature on the properties and water-splitting behavior of photocatalysts were investigated. Characterization results showed that hydrolysis temperatures higher than 40 °C induce the formation of the rutile phase and particle agglomeration, reduce the N-dopant content, and decrease the range of visible-light absorption. In this study, a low hydrolysis temperature of about 20 °C is optimal for the sol–gel preparation of N-doped TiO$_{2}$; this temperature favors the formation of high-purity anatase, small particle size, extensive visible-light absorption, and excellent rates of photocatalytic production of H$_{2}$ (about 2100 μmol h$^{−1}$ g$^{−1}$).
