A Review of Metal–Organic Frameworks Derived Hollow‐Structured Photocatalysts: Synthesis and Applications

Abstract Photocatalysis is a most important approach to addressing global energy shortages and environmental issues due to its environmentally friendly and sustainable properties. The key to realizing efficient photocatalysis relies on developing appropriate catalysts with high efficiency and chemical stability. Among various photocatalysts, Metal–organic frameworks (MOFs)‐derived hollow‐structured materials have drawn increased attention in photocatalysis based on advantages like more active sites, strong light absorption, efficient transfer of pho‐induced charges, excellent stability, high electrical conductivity, and better biocompatibility. Specifically, MOFs‐derived hollow‐structured materials are widely utilized in photocatalytic CO 2 reduction (CO 2 RR), hydrogen evolution (HER), nitrogen fixation (NRR), degradation, and other reactions. This review starts with the development story of MOFs, the commonly adopted synthesis strategies of MOFs‐derived hollow materials, and the latest research progress in various photocatalytic applications are also introduced in detail. Ultimately, the challenges of MOFs‐derived hollow‐structured materials in practical photocatalytic applications are also prospected. This review holds great potential for developing more applicable and efficient MOFs‐derived hollow‐structured photocatalysts.
