Symposium NM03-Rational Designed Hierarchical Nanostructures for Photocatalytic Systems

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.

This symposium provides an international platform to present and discuss the latest research and prospective activates on the photocatalytic materials. This program will address latest advances in new narrow band gap photocatalysts design and construction, hierarchical nanostructures for heterojunction and Z-Scheme, fundamental understanding of photocatalytic mechanism, and theoretical modeling and simulation. Part of this symposium has a joint session with Symposium titled “Multi-scale designing and constructing photocatalytic materials for solar fuels”.

This symposium brings together top leaders in science and technology, interested newcomers and world-wide experts; and it would further expand the interest and progress in this area.
