Synergistic Effect of Bi2WO6 Nanoplates and Co3O4 Cocatalyst for Enhanced Photoelectrochemical Properties

Abstract

Herein, we demonstrated the controllable fabrication of Bi2WO6 nanoplate arrays decorated with Co3O4 cocatalysts through the combination of hydrothermal reaction with annealing treatments. The synergistic effect of bulk charge transport and surface oxygen evolution could significantly improve the photoelectrochemical properties (0.45 mA/cm2, 1.23 VRHE) for water splitting under simulanted solar light, which is much higher than that of traditional Bi2WO6 particles photoanodes (0.02 mA/cm2, 1.23 VRHE). These demonstrations clearly reveal that the rational construction of photoanode structure and selective decoration of oxygen evolution cocatalysts could serve an alternate strategy toward the development of highly efficient water splitting system.
