Hydrothermal synthesis of In2O3-loaded BiVO4 with exposed {010} {110) facets for enhanced visible-light photocatalytic activity
Under the strategies of the morphology engineering method and the heterojunction construction, In2O3/BiVO4 composites with different molar ratios were prepared through a simple two-step hydrothermal route. The as-prepared monoclinic BiVO4 showed a truncated bipyramid shape with high exposed {010} {110} facets, on which the hexagonal In2O3 nanoparticles were grown, leading to the formation of a heterojunction structure. Due to the high-active exposure facets of BiVO4 and the improved photogenerated carriers separation efficiency of the formed heterojunction, In2O3/BiVO4 exhibited excellent visible -light photocatalytic activity in the degradation of rhodamine B.
