Abstract
0D/2D photocatalysts have aroused concern due to the high charge mobility. Herein, a 0D/2D structure is formed by employing a facile method to disperse Fe2O3 Quantum-Dots (QDs) on 2D-C3N4 without aggregation at a relatively low temperature of 200 °C. The ultrathin monolayer 2D structure, highly dispersed Fe2O3 QDs, the strong coupling as well as quantum-sized confinement effect between them lead to superior visible-light-driven photocurrent performance and photocatalytic activity. Particularly, the 0.5% Fe2O3 QDs/2D-C3N4 composite exhibits the highest photocatalytic activity under visible light. More importantly, the 0D/2D photocatalysts show superior durability with little photocatalytic activity decline in the circular reaction for the photocatalytic degradation of organic pollution. Therefore, this work supplies a new opportunity to construct multifunctional 0D/2D photocatalysts for degradation of pollutants in water.
