Abstract:
An all-inorganic quasi-homogenous photocatalytic H2 evolution system has been developed employing Keggin-type polyoxometalate H4SiW12O40 (SiW12) as the photosensitizer and [Mo3S13]2- clusters as the catalyst. This SiW12/[Mo3S13]2- system achieves a high turnover number (TON) of 922 based on the [Mo3S13]2- catalyst in 5 h of reaction and excellent H2 evolution stability for 40 h with a high turnover number of 6876.
