Abstract

Construction of semiconducting metal-organic framework based heterostructures is emerging as a promising strategy for enhancing their photocatalytic performances. Here, tetrapod-like NH₂-MIL-125@ZnS heterostructures with tunable heterojunction coverage and well-matched band structure are synthesized as photocatalysts. When used for photocatalytic O₂ reduction reaction, a heterojunction coverage of ≈45.1% leads to the best performance with a hydrogen peroxide production rate of ≈120 mm g⁻¹ h⁻¹, outperforming control samples with either larger or smaller heterojunction coverages and most reported MOF based photocatalysts in similar reaction systems.
