Nature‐Inspired Environmental “Phosphorylation” Boosts Photocatalytic H 2 Production over Carbon Nitride Nanosheets under Visible‐Light Irradiation

Inspired by the crucial roles of phosphates in natural photosynthesis, we explored an environmental “phosphorylation” strategy for boosting photocatalytic H 2 production over g‐C 3 N 4 nanosheets under visible light.

Description
Summary:Inspired by the crucial roles of phosphates in natural photosynthesis, we explored an environmental “phosphorylation” strategy for boosting photocatalytic H 2 production over g‐C 3 N 4 nanosheets under visible light. As expected, a substantial improvement was observed in the rate of H 2 evolution to 947 μmol h −1 , and the apparent quantum yield was as high as 26.1 % at 420 nm. The synergy of enhanced proton reduction and improved hole oxidation is proposed to account for the markedly increased activity. Our findings may provide a promising and facile approach to highly efficient photocatalysis for solar‐energy conversion.
