Band-gap engineering of Bi-MOFs via anthraquinone integration for boosting photocatalytic H 2 O 2 production over a donor–acceptor–acceptor junction

under visible light, which is approximately 3.3 times higher than that of pure RF and 205 times higher than that of the pristine Bi-MOF. Structural and photoelectrochemical characterizations collectively confirm the successful formation of the junction and the pivotal role of anthraquinone in electronic structure engineering. This work provides a profound insight into the design of high-performance photocatalysts through precise band-structure manipulation for sustainable chemical synthesis.
