Harnessing Hydrogen Spillover by Lattice Strain for Enhanced Photocatalytic Hydrogen Evolution of ZnIn 2 S 4

Hydrogen spillover has been believed to play an essential role in the reaction path in photocatalysis, yet its rational regulation remains a considerable challenge for the design of highly efficient photocatalysts. Herein, hydrogen spillover can be well regulated at ZnIn2S4 with surface decorated by cubic α-MoC1–x quantum dots (QDs) with different lattice strain (ZIS/QDs). With the increasing lattice strain of α-MoC1–x, the composite shows first increased and then decreased photocatalytic hydrogen evolution (PHE). Spectroscopic characterizations and calculation analysis indicate that PHE performance of ZIS/QDs is highly corelated with hydrogen spillover rather than charge transfer process. Further systematic…
