Abstract
Novel Bi2S3/BiOBr nanocomposites (NCs) were prepared via L-Cysteine-assisted hydrothermal avenue as efficient photocatalysts to degrade rhodamine B (RhB). As a result, the obtained Bi2S3/BiOBr NCs exhibited the slice-like microstructure with the average diameters of ca. 100 nm. The elemental analysis of X-ray photoelectron spectroscopy indicates that the nanocomposites were combined by Bi2S3 and BiOBr. Then, the photo-induced degradation of RhB was performed with a Xenon lamp to simulate the sunlight ([Formula: see text] 400 nm) and the photo-decomposition rate was calculated. The following results showed that the Bi2S3/BiOBr NCs possessed excellent photocatalytice performance, which was better than that of other samples as control. Thus, this avenue provides a new reference for the facile synthesis of photocatalysts with low cost and high efficiency.
