BiPO4／BiVO4复合材料的制备及可见光催化活性
Preparation of BiPO4/BiVO4 Composites with High Visible-light Photocatalytic Activity†
摘要
Abstract
BiPO4/BiVO4 composites were prepared by combining hydrothermal and solvothermal synthetic methods. Field emission scanning electron microscopy( FESEM) and transmission electron microscopy( TEM) revealed that the as-prepared BiVO4 exhibited a truncated bipyramid morphology with high {010}, {110}exposed facets, and that the as-obtained BiPO4 nanoparticles were grown on the surface of BiVO4, leading to the formation of the BiPO4/BiVO4 heterojunction. The transient photocurrent-time behaviors indicated that the formed heterojunction made the transfer and separation of the photo-generated carriers more efficient. The as-synthesized BiPO4/BiVO4 composites exhibited high photocatalytic activities in the degradation of rhoda-mine B under visible-light irradiation. It was found that the sample prepared with a BiPO4/BiVO4 molar ratio of 3∶10 in the reactants showed the best performance.关键词
