Mo–S bridged ZnIn2S4/Bi2MoO6 S-scheme heterojunction photocatalyst for efficient H2O2 production

Nano Research
Sulfide-based photocatalysts hold promise for visible-light-driven H2O2 synthesis; however, the low efficiency of photogenerated charge carrier separation and migration remains a critical bottleneck limiting their overall yield.
