Renewable and Commercially Viable Porous Material-Supported Heterojunction Nanocomposites as UV-Visible Light-Responsive Photocatalysts for Environmental and Energy-Related Applications
摘要
The chapter deals with porous material-based nanocomposites as visible light active photocatalyst monoliths to remove lingering contaminants from the environment. Porous materials with well-defined, tailor-made structural and surface properties offer numerous applications related to catalysis, adsorption, separation, biomedicines, energy technologies, etc. In heterogeneous photocatalysis, porous materials such as zeolites, porous metal oxides, metal-organic frameworks, and porous polymer monoliths supported by nanocomposites contribute intensely to environmental and energy-related applications. Porous photocatalysts with a hierarchical stricture show great promise due to their distinct features compared to solid structures. These advantages encompass improved scattering and adsorption of light, abundance reaction sites, large specific surface areas, enhanced facilitation of mass and charge transfer, etc. These porous materials are efficient for hosting photoactive materials and are versatile owing to their lower production cost, high-performance efficiency, easy modification, and renewability. The chapter discusses the advances in heterogeneous photocatalysis using hierarchically porous materials as photocatalytic supports and their prospects in environmental decontamination and energy-related applications.
