Recent Advances in the Synthesis and Photoelectrocatalysis of Zeolite-Based Composites

Zeolites are a class of porous aluminosilicates possessing high surface area, good hydrothermal stability, strong sorption, and high ion-exchanging potential, and which frequently serve as efficient catalytic materials. The composites which integrate zeolite with alternative substances like metal oxides or carbon-based materials steadily outperform individual constituents. Recently, the application of zeolite-based composites in the field of photocatalytic oxidation and electrocatalytic oxidation/reduction, which is mainly focused on pollution treatment in sewage and air, have garnered significant attention. Several synthesis strategies for zeolite-based composites including post-treatment and in situ hydrothermal synthesis methods are explicated. Meanwhile, multifarious types of zeolite-based photoelectric catalytic composites are also summarized. Finally, we highlight the advancements improving the performance of zeolite-based composites in the photocatalytic treatment of organic pollutants in wastewater and the electrocatalytic reduction of CO2 and organics.
