文摘
We demonstrate appreciable hydrogen generation by coupling biomimetic carbonation with common metal driven plasmonic photocatalysis. It’s a new and unique enzyme driven approach for non-noble metal and organic donor free based hydrogen generation. The novel and unreported steps include i conversion of proton from biomimetic carbonation reaction to high value added product like hydrogen ii oxidation of zinc and usage of in-situ generated Zn/ZnO for photothermal reaction. The system has shown hydrogen evolution rate of 1238 μ mol h−1.
