It has been proposed that hollow structures can utilize solar energy efficiently, which is attributed to the fact that sunlight is repeatedly refracted in hollow materials, and thus improving the utilization of solar energy.
Hollow structures are undoubtedly a powerful structure for improving energy conversion due to the increased specific surface area, solar light utilization, and exposure of active centers, but there are still some challenges to be addressed for the synthesis and deeper understanding of hollow structured semiconductors for practical applications.
The application of hollow photocatalysts for solar energy conversion is reviewed. The potential directions for hollow photocatalysts are proposed. The development of high-efficient photocatalysts plays an important role in the sustainable utilization of solar energy.
Therefore, hollow structure oxide photocatalysts have good application prospects in the process of solar energy utilization, but their thickness limits the scope of application. Therefore, in future development, thinner photocatalysts with hollow structures may be favorable for the improved applicability.
Hollow nanostructured photocatalysts are vital for solar light utilization and charge carrier separation in photocatalytic processes. Therefore, the construction of hollow semiconductor photocatalysts is a promising strategy for preparing novel high-efficient photocatalysts.
First, hollow photocatalysts consist of nanoparticles, which can significantly improve charge separation. Owing to the high surface area, short path, and large number of active sites, reducing the size to the nanometer scale has a considerable effect on the separation of photogenerated electron−hole pairs .
