Semiconducting metal-organic framework based heterostructures with tunable heterojunction coverage and well-matched band structure were synthesized and used as photocatalysts for O-2 reduction reaction, achieving a high hydrogen peroxide production rate.
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 O-2 reduction reaction, a heterojunction coverage of approximate to 45.1% leads to the best performance with a hydrogen peroxide production rate of approximate to 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.
