Symposium ES10—Rational Design Hierarchical Nanostructures for Photocatalytic System
Photocatalysis plays an important role in a diverse range of applications including emerging technology related to clean energy, sustainable environment and petrochemical industry such as water splitting, CO2 reduction, nitrogen fixation, pollutant treatment, energy conversion and organic reaction. In nature, photosynthesis is achieved broad light absorption and highly efficient charge transfer process by constructing hierarchical nanostructure. Heterojunction and Z-scheme systems based on rational designed hierarchical nanostructure materials have been emerged in the solar energy conversion to enhance photogenerated charge separation and transfer efficiency. It further reaches efficiently convert solar energy into chemical energy. Furthermore, understanding the photophysical process of interface between two semiconductors in heterojunction and Z-scheme, between semiconductor and liquid, will be beneficial to the design of hierarchical photocatalytic materials. In this sense, rational design and preparation of photocatalytic materials with tailored structure and functions, deep understanding both materials’ work mechanism and interfacial between solid/solid and solid/liquid properties are crucial for the development of novel photocatalytic materials, devices and system.
