英文摘要: Photocatalysis is considered as an important solution, which contributes greatly to sustainable energy generation and environmental remediation. This project aims to address the issues of inefficient visible-light absorption and the difficulties in manufacturing large-area, flexible devices related to the existing photocatalytic systems, and hence puts forward the novel large-area organic nanocrystal-graphene hybrid system. The hybrid system can make concurrent use of the efficient photofunctional organic absorbers, and the favorable chemical stability, conductivity, charge carrier separation efficiency, large specific surface area provided by the large-area graphene film, to develop ‘nanohybrid film photocatalytic system’ that can be applied in wide spectrum responsive, large-area, flexible photoelectric devices for photoelectrochemical water splitting and photodegradation. It promises to provide the theoretical and experimental basis for the development of novel, high-performance photocatalytic film system.
