In the paper, the effects of polyvinylpyrrolidone (PVP) concentration and chemical wet etching on morphologies and phase composition of CuSbS₂ particles synthesized by microwave irradiation method were investigated. The phase structure, morphologies, and optical and photocatalytic properties were analyzed by using characterization techniques. The results showed that the morphology of as-prepared particles was spherical and the shape of particles etched in Na₂S solution was tetragonal rod-like structure. The optical band gap of the particles with 1.5 g PVP after chemical etching was about 1.41 eV. The photocatalytic performance of CuSbS₂ could be significantly improved after Na₂S chemical etching. The amounts of PVP had an obvious influence on specific surface area of as-synthesized CuSbS₂ particles. The CuSbS₂ particles with 1.5 g PVP had the best photocatalytic performance after chemical etching treatment, and the C/C₀ value reached 0.36.

研究了聚乙烯吡咯烷酮（PVP）的浓度和化学湿法刻蚀对微波辐射法合成的CuSbS ₂颗粒的形貌和相组成的影响。通过使用表征技术分析了相结构，形态，光学和光催化性能。结果表明，所制得的颗粒形态为球形，在Na ₂ S溶液中刻蚀的颗粒为四方棒状结构。化学蚀刻后，具有1.5 g PVP的颗粒的光学带隙约为1.41 eV。Na _2处理后，CuSbS ₂的光催化性能可以显着提高。S化学蚀刻。PVP的量对合成的CuSbS ₂颗粒的比表面积有明显的影响。1.5 g PVP的CuSbS ₂颗粒经过化学刻蚀处理后具有最好的光催化性能，其C / C ₀值为0.36。
