In this presentation, Bi2S3/BiOCl nanoparticles with excellent photocatalytic capacity were in-situ construct by a hydrothermal approach using 3-mercaptopropionic (3 M) acid. 3 M acid can provide S source for Bi2S3 and modify BiOCl at the same time. In-situ construction of Bi2S3/BiOCl composites can induce BiOCl to form thin sheets, facilitating the segregation of photoactivated carriers. Under the irradiation of a 500 W Xe lamp, Bi2S3/BiOCl has better catalytic capability than BiOCl for removal of Rhodamine B (RhB) and Cr (VI). The catalytic capability of Bi2S3/BiOCl is 2.5 and 2.9 times of that of BiOCl toward abatement of RhB and Cr (VI), respectively.
