Constructing BiOBr/CoOx/g-C3N4 Z-scheme photocatalyst with CoOx as both redox mediator and cocatalyst for phenol degradation

Constructing Z-scheme heterostructure photocatalysts is an efficient method to improve the photocatalytic performance for degrading organic pollutants. Herein, the BiOBr/CoOx/g-C3N4 Z-scheme photocatalyst was constructed by integrating two-dimensional (2D) BiOBr and g-C3N4 components with introducing CoOx as both redox mediator and cocatalyst. The spectroscopic and photoelectrochemical analyses verified the higher efficiency of charge transfer...
