Abstract: With the rapid development of industry and the increasing energy demand caused by population growth, the extensive utilization of fossil fuels results in serious environment pollution and energy crisis, which are threatening the survival and development of human society. Photocatalysis has been considered as one of the most potential techniques to solve the environment and energy problems owing to the use of green solar energy as source. Under solar light illumination, light energy can be converted to chemical energy over photocatalyst for environmental remediation and clean energy production. Therefore, photocatalysis has attracted great attention in the world wide. The core of photocatalysis is photocatalyst. In the past decades, with the development of preparation technology and the in deep understanding of photocatalysis, the kinds of photocatalyst have been broadened from TiO2 to various kinds of metal oxide, sulfide, nitride and metallic element, nonmetal and organic photocatalyst. And its application has also spread from aqueous environmental remediation and water splitting to organic synthesis and various gas-phase reaction, including NO oxidization, CO2 reduction, CH4 activation and so on. Current reports focus on the photocatalytic activity. However, most of the reported photocatalysts are in powder form, which has strong tendency to agglomerate. In the practical application, only the surface of photocatalyst powder can adsorb pollutant and absorb light, and most photocatalyst has no contribution to photocatalysis, thus resulting in low photocatalytic activity. On the other hand, photocatalyst powder will scatter to everywhere and inevitably get lost under gas or water flow, increasing the difficulty of recovery operation and leading to serious secondary pollution. Recently, monolithic photocatalyst has attracted great attention. Monolithic photocatalysts usually possesses abundant porous structure and large surface area, which can increase the contact area of pollutant and the utilization of light energy. Moreover, their monolithic properties significantly improve the operability and simplify the recovery process. With the development of preparation technology, the types of monolithic photoca-talysts have broadened from homogeneous aerogel photocatalysts to monolithic hybrid photocatalysts. Meanwhile, their application has also spread from physical adsorption to photocatalytic reaction, including environmental remediation and clean energy production. In this review, we summarize the preparation strategies and applications of monolithic photocatalysts. In particular, we highlight recent developments for the construction of aerogel photocatalyst and grafting photocatalyst to monolithic substrates, as well as update applications on the removal of aqueous pollutants, gas pollution remediation, water splitting and photocatalysis CO2 conversion.
