Nanoarchitecture of a Two-Dimensional Few-Layer Graphene Oxide/π-Conjugated Polyimide Composite for Enhanced Photocatalytic Performance

Abstract

A novel two-dimensional graphene oxide/sulfurdoped polyimide (GO/SPI) hybrid polymer photocatalyst was synthesized by a facile ultrasonic chemical method. The characterization results showed that the skeleton structure of SPI was not changed when the few layers of GO were wrapped on the surface. Due to the excellent charge transport characteristics of GO and the strong π−π stacking interaction between two-dimensional GO and SPI, the photogenerated carrier transport capability of the GO/SPI composites was significantly enhanced compared with that of SPI. The efficient transmission and separation of photogenerated charge carriers significantly improve the photocatalytic degradation of the methyl orange activity of the GO/SPI composite. This work provides a facile and new way for the synthesis of metal-free inorganic− organic composite photocatalysts with high efficiency and low cost.

“…However, polyimide still has some defects for organic degradation and organic synthesis, among which photogenerated electron transport efficiency and visible light excitation are the two key problems that polyimide fails to show excellent photocatalytic performance. Therefore, a range of strategies, including heterojunction, [7] co‐catalyst loading, [8] and heteroatom doping, [9] have been used to improve the photocatalytic efficiency of PI.…”
