However, medical demand is calling for more effective and convenient H 2 O 2 preparation method. Photocatalysis can effectively produce H 2 O 2 with simple process and easy access catalyst. This article presents a synergistic strategy which combines the advantages of defect engineering and heterojunction to achieve optimal performance. Acetic acid is applied as modulator to introduce linker defect and UiO‐67 in‐situ grows on surface to build type‐II heterojunction. The defect level was quantified with 1 H NMR (nuclear magnetic resonance) and transmission electron microscope convince successful combination. Synergistic effect of defect engineering and heterojunction significantly improves photocatalytic performance and achieves 3.92‐fold higher photocatalytic H 2 O 2 evolution rates. Photoelectrochemical characterization indicates defect engineering and type‐II heterojunction bring about high photo‐absorption, carrier separation, and photoelectron response. This article provides a perspective that synergistic effect of defect engineering and heterojunction can increase photocatalytic performance from overall process. 10.1002/cctc.70713 http://onlinelibrary.wiley.com/termsAndConditions#vor |
