BiOBr/BiOCl flowerlike composites were successfully synthesized in different solutions containing 0.00–1.50 g polyvinylpyrrolidone (PVP) by microwave-assisted hydrothermal method. The as-synthesized BiOBr/BiOCl composites were studied by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, UV–visible diffuse reflection spectroscopy, photoluminescence spectroscopy, electrochemical impedance spectroscopy and photocatalysis. In this research, the morphologies of tetragonal BiOBr and tetragonal BiOCl products were transformed from BiOBr/BiOCl microplates without PVP into BiOBr/BiOCl microflowers with 1.00 g added PVP. The BiOBr/BiOCl microflowers have optimal visible light absorption and demonstrate excellent photocatalytic activity in degradation of rhodamine B and salicylic acid under xenon radiation. These composites are promising materials used for wastewater treatment.

通过微波辅助水热法成功地在含有0.00-1.50 g聚乙烯吡咯烷酮（PVP）的不同溶液中成功合成了BiOBr / BiOCl花状复合材料。通过X射线衍射，场发射扫描电子显微镜，透射电子显微镜，X射线光电子能谱，傅里叶变换红外光谱，拉曼光谱，紫外可见漫反射光谱，光致发光光谱，电化学阻抗谱和光催化。在这项研究中，将四边形BiOBr和四边形BiOCl产品的形态从无PVP的BiOBr / BiOCl微孔板转化为添加了1.00 g PVP的BiOBr / BiOCl微花。BiOBr / BiOCl微型花具有最佳的可见光吸收率，并在氙辐射下对若丹明B和水杨酸的降解表现出出色的光催化活性。这些复合材料是用于废水处理的有前途的材料。
