Solar-light-driven H(2) production in water with a [NiFeSe]-hydrogenase (H(2)ase) and a bioinspired synthetic nickel catalyst (NiP) in combination with a heptazine carbon nitride polymer, melon (CN(x)), is reported. The semibiological and purely synthetic systems show catalytic activity during solar...

Sumario:Solar-light-driven H(2) production in water with a [NiFeSe]-hydrogenase (H(2)ase) and a bioinspired synthetic nickel catalyst (NiP) in combination with a heptazine carbon nitride polymer, melon (CN(x)), is reported. The semibiological and purely synthetic systems show catalytic activity during solar light irradiation with turnover numbers (TONs) of more than 50 000 mol H(2) (mol H(2)ase)(−1) and approximately 155 mol H(2) (mol NiP)(−1) in redox-mediator-free aqueous solution at pH 6 and 4.5, respectively. Both systems maintained a reduced photoactivity under UV-free solar light irradiation (λ>420 nm).
