ZnIn2S4 (ZIS) is widely used in the field of photocatalytic hydrogen production due to its unique photoelectric properties. Nonetheless, performance ZIS usually faces problems poor conductivity and rapid recombination charge carriers. Heteroatom doping often regarded as one effective strategies for improving catalytic activity photocatalysts. Herein, phosphorus (P)-doped was prepared by hydrothermal method, whose energy band structure were fully studied. The gap P-doped about 2.51 eV, which slightly smaller than that pure ZIS. Moreover, upward shift band, reduction ability enhanced, also exhibits stronger optimized a rate 1566.6 μmol g-1 h-1, 3.8 times pristine (411.1 h-1). This work provides broad platform design synthesis phosphorus-doped sulfide-based photocatalysts evolution.

Photocatalytic hydrogen evolution (PHE) via water splitting using semiconductor photocatalysts is an effective path to solve the current energy crisis and environmental pollution. Heterojunction photocatalysts, containing two or more semiconductors, exhibit better PHE rates than those with only one owing altered band alignment at interface stronger driving force for charge separation. Traditional binary metal sulfide (BMS)-based heterojunction such as CdS, MoS

It is desirable to regulate charge migration synergistically via atomic level decoration because it can construct active sites with both thermodynamic and kinetic advantages in photocatalytic hydrogen (H2) evolution. Here, a mild cation exchange-mediated strategy was applied anchor palladium (Pd) cations the ZnIn2S4 nanostructure, achieving an outstanding H2 evolution rate of 1236.4 μmol h–1 (λ ≥ 420 nm) accompanied by apparent quantum efficiency 60.06% = nm). Pd dopants act as surface chemical state modulators, which help balance *H adsorption thermodynamically. More importantly, situ electron spin resonance XPS analysis reveal that synergistic interaction brought Pd–S structure constructs efficient transfer channel, leading more delocalized photocarriers for reaction. A feasible proposed this study improve performance photocatalysts from viewpoint exchange. Simultaneously, verified modulate accumulation at substitution sites, providing substantiation unique insights into electronic modification photocatalysts.
