A Covalent Organic Framework as Photocatalyst for Smart Conversion Between Photooxidation and Photoreduction and H 2 O 2 Production in Full pH Environment

Abstract
Abstract Developing multifunctional photocatalysts with intelligent self‐adjusting is of great significance in the photocatalytic process. Herein, a smart covalent organic framework (Por‐HQ‐COF) with a phenol‐quinone conversion structure with pH changes is constructed for photooxidation, photoreduction, and H 2 O 2 production. As a smart photocatalyst, Por‐HQ‐COF can convert into Por‐BQ‐COF intelligently with a trigger including solution pH, and vice versa. The reconstruction of phenol‐quinone conversion not only significantly alters the morphologies and the specific surface areas of the COF, but also leads to an entirely change in the band energy and charge distribution to influence photoelectric properties.…
