The advanced development of floatable photocatalysts: Preparation, advantages, and application

As a new type of photocatalyst, the floatable photocatalyst has the advantages of easy recovery, excellent stability, and enhanced photocatalytic efficiency, which has been paid extensive attention in recent years. This paper mainly reviews the latest advanced progress of floatable photocatalysts from the preparation to application. Firstly, we briefly introduced the preparation methods of floatable photocatalysts. Then, we analyzed the advantages of the floatable photocatalytic system in some aspects such as rapid gas phase reactant transport, enhanced light utilization, convenient recovery, excellent stability and reusability et.al. Subsequently, the application progress of floatable photocatalysts in the fields of hydrogen production, H2O2 production, ammonia degradation, and pollutant treatment was summarized in detail. Finally, we sorted out the conclusions and outlook, aiming to provide new insights for its development.
