Effect of reaction atmosphere on photodeposition of Pt nanoparticles and photocatalytic hydrogen evolution from SrTiO3 suspension system

A long induction period which is hardly found in close-system appears in presence of oxygen, and is affected by the concentration of chloroplatinic acid. The hydrogen evolution rate increased and reached a platform with increasing the Pt coverage on the surface of photocatalyst which is characterized by the Pt:Ti atomic ratio.159
