Synthesis of 2D WO3/Cu2O heterojunction nanosheet arrays with enhanced photocatalytic degradation activity and photoelectrochemical performance
Source abstract
Abstract
The construct of close interface contacts and effective separation of photogenerated carriers is an effective strategy to enhanced the photocatalytic and photoelectrochemical properties of heterostructures. In this paper, the 2D WO3/Cu2O heterojunction nanosheet arrays were synthesized by one-step hydrothermal method and electrochemical deposition technology. The Cu2O nanoparticles deposited on WO3surface enhanced the visible light absorption capacity and improved the separation efficiency of photogenerated carriers. The WO3/Cu2O heterostructures significantly enhanced the photocatalytic degradation and photoelectrochemical activity, in which the reaction kinetic constant and photocurrent density of WO3/Cu2O-60 s is nearly 3.3 times and 5 times higher than that of WO3, respectively. The enhanced photocatalytic and photoelectrochemical performance is mainly due to the formation of pn-junctions at the interface of WO3/Cu2O heterojunction, which improves the collection of visible light and enhances the separation of electron–hole pairs.Graphical abstractThe WO3/Cu2O heterojunction nanosheet arrays for efficient photocatalytic degradation RhB and photoelectrochemical water splitting.
