Zeolite-based Photocatalysts: A Promising Strategy for Efficient Photocatalysis

A photocatalyst is generally defined as a material that has the capability to induce chemical reactions of substances of interest adsorbed on the surface by light-generated active radicals [1]. The efficiency of the photocatalyst is a function of the balance between charge separation, ease of interfacial electron transfer and energywasting charge recombination [2]. With the inspiration of improving photocatalysis efficiency and selectivity, people are trying hard to develop new photocatalysts. Zeolites are crystalline nanoporous inorganic materials with well-defined interconnected channels or cavities in the nanometre or subnanometer length scale, termed as micropores (0.5-2 nm) [3,4]. With the uniform pore size, polar environment, high surface area, the internal active sites and excellent adsorption capability [5], zeolites could enhance the efficiency and selectivity of photocatalysts either by photoactiving the zeolite framework or by encapsulating with semiconductor oxides.
