Efficient Charge Separation between Bi and Bi2MoO6 for Photoelectrochemical Properties

 
Abstract: Herein, porous Bi/Bi2MoO6 nanoparticles have been prepared by a facile in-situ reduction approach. Moreover, the morphology and Bi content of product could be controlled by varying the reaction time. By controlled fabrication, the desired porous Bi2MoO6 nanostructure with incorporation of Bi was obtained and exhibited high photoelectric and photocatalytic activity. In particular, the samples yield a photocurrent density of 320 mu A cm(-2), which is 3.2 times that of the pure Bi2MoO6 nanosheet (100 mu A cm(-2)) under the same conditions. UV/Vis diffuse reflectance spectroscopy analysis confirmed the surface plasmon resonance in the as-prepared porous nanoparticles. The improved photoelectric properties could be the synergistic effect of the porous structure with large surface area and effective electron-hole separations between Bi and Bi2MoO6.
