摘要

Abstract

A simple and high efficient method was proposed for the synthesis of uniform three dimensional (3D) BiVO

/reduced graphene oxide (RGO) nanocomposite photocatalyst by adopting the microwave assistant and using Bi (NO

)

·5H

graphene oxide (GO) and NH

as precursor. The as-obtained composites were well characterized with the aid of various techniques to study the morphology

structure

composition

optimal and electrical property. In the as-obtained composites

the GO sheets were fully reduced into RGO

and monoclinic structure BiVO

crystallized completely into butterfly-like BiVO

lamellas and well bonded with the RGO lamellas. The length and the width of the butterfly-like BiVO

particle were about 1.5 μm

and the thickness of the flake was about 20 nm. Photocatalytic performances of BiVO

/RGO composite and pure BiVO

particle have been evaluated by investigating the reduction of Cr(VI) ion-contained wastewater under simulated solar light irradiation

where the BiVO

/RGO composite displayed enhanced photocatalytic activity. It is found that the pseudo-firs

t-order rate constants (k) for the photocatalytic reduction of Cr (VI) by BiVO

/RGO composite was about 4 times as high as that of the pure BiVO

. The present work suggested that the combination of BiVO

and RGO displayed a remarkable synergistic effect

which led to enhanced photo-catalytic activity on Cr(VI) reduction.
