<jats:title>Abstract</jats:title> <jats:p>The photocatalytic H2 evolution by Pt-loaded TiO2 was examined using sacrificial agents such as 1,2-ethanediol, glycerol, erythritol, and arabitol, the carbons of which all have hydroxy groups. In these cases, almost complete decomposition of sacrificial agents into CO2 and H2O occurred. Moreover, the H2 evolution reached the maximum values estimated by their potentially electron-donating ability. On the other hand, smaller amounts of CO2 and H2 were evolved from 1,2,3-butanetriol, 1,2,4-butanetriol, and 1,2-butanediol, which had both continuous hydroxylated carbons and one or two non-hydroxy-substituted carbons, the inner continuous 2,3-butanediol, and the discontinuous 1,3- and 1,4-butanediols. In the cases of monools such as 2-butanol and 2-propanol, CO2 was not evolved at all. Thus, we found that the structure of sacrificial agents, more so than the potential electron-donating ability, is an important factor to evolve H2 efficiently.</jats:p>
