Abstract

Abstract: A homogeneous system containing 4-(4-tolyl)-6-phenyl-2, 2'-bipyridyl platinum(Ⅱ) chloride 1 as a photosensitizer, a bis(dimethylglyoximate) Co(Ⅲ) complex as a catalyst, and TEOA as a sacrificial electron donor is designed for H₂ generation from water. With visible light irradiation(λ > 400 nm) for 19 h, more than 804 equivalents of H₂ per photosensiter were achieved, which is competitive with that obtained by platinum(Ⅱ) terpyridyl acetylide complex.

Key words: 4-(4-tolyl)-6-phenyl-2, 2'-bipyridyl platinum(Ⅱ) chloride, Co(Ⅲ) complex, photosensitizer, photocatalytic hydrogen production, turnover number
