摘要：

Designing surface phase is an efficient strategy to facilitate charge separation and photocatalytic H 2 -evolution performance. In this work, CoS cocatalysts were intimately anchored on Cd 0.5 Zn 0.5 S (denoted as CZS) photocatalyst via in-situ precipitate transformation in S 2− /SO 3 2− solution with cobaltous phosphate (CoPi) as a precursor, meanwhile, S 2− ions were adsorbed on the CZS to form a sulfur-rich surface (denoted as CZS-S). The photocatalytic H 2 -evolution rate of CoS/CZS-S is 2.02 mmol·g −1 ·h −1 in 0.1 M Na 2 S/Na 2 SO 3...
