An all-inorganic quasi-homogenous polyoxometalate/[Mo3S13]2− system for efficient and stable photocatalytic H2 evolution

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.
