- A catalytic system for H2 evolution is built by CdS, a Ni complex and H2A.
- This system achieves 70,970Â mol of H2 per mol of catalyst during 70Â h irradiation.
- The average value of AQY was ~Â 18% during 10Â h of irradiation.
- A cycle for H2 production by the photocatalytic system is afforded.
In this paper, we present a nickel complex, [BzPyN(CH3)2]2[Ni(mnt)2] 1 (mnt2 â = maleonitriledithiolate), a cocatalyst for building a photocatalytic system for H2 generation from water. Under photoirradiation with blue light (λmax = 469 nm), 1, together with CdS nanorods (CdS NRs) as a photosensitizer, and ascorbic acid (H2A) as a sacrificial electron donor in a pH 2.5 aqueous solution, produces hydrogen with a turnover number (TON) of 70,970 mol of H2 per mol of catalyst during 70 h irradiation and the average value of AQY is ~ 18% during 10 h of irradiation.
