Photo-deposition of dual Ni(OH)₂ and Ni_xP cocatalysts on ZnIn₂S₄/ZnS for efficient photocatalytic hydrogen production.

ABSTRACT: Efficient photocatalytic hydrogen production from water splitting remains a critical challenge for sustainable energy solutions. Here, we report dual Ni(OH)₂ (NO)/Ni_xP (NP) cocatalysts photo-deposited and ZnS decorated ZnIn₂S₄ photocatalyst (NOP/ZIS-Z). It exhibits efficient photocatalytic hydrogen production (PHP) with the rate of 5.46 mmol·g^-1·h^-1 and 420 nm quantum yield of 55.2% in triethanolamine (TEOA) system upon Xe lamp visible light combined with excellent stability. Impressively, its PHP rate reaches 0.54 mmol·g^-1·h^-1 in pure water under natural sunlight, showing tremendous practical potentials. The synergistic mechanism among ZnS, NO, and NP was revealed: (i) ZnS could transfer electron from
