Facile synthesis of highly efficient photocatalysts based on organic small molecular co-catalyst

Abstract

A new metal-free organic molecular as co-catalyst was developed, which could drastically enhance the photocatalytic performance of photocatalyst (eg. g-C 3 N 4 , MoS 2 and TiO 2 ). The enhancing photocatalytic activity was evaluated for photocatalytic degradation of organic dyes. It showed ultra-high photocatalytic rate (4.17 mg/g·min) and ultra-short time (about 6.0 min) for photocatalytic degradation of organic dyes (25 mg/ml). The enhanced photocatalytic performance was attributed to suppress recombination of photogenerated charges and provide a new photoredox reaction pathway under molecular co-catalyst assistance. The study represents a facile method to develop ultra-effectively photoca..
