摘　　要：以BiOI为载体负载K-C_(3)N_(4),用共沉淀法制备了一系列质量比不同的BiOI/K-C_(3)N_(4)复合材料。采用扫描电子显微镜、紫外-可见漫反射光谱仪、X射线衍射仪和光电化学测试等方法,对BiOI/K-C_(3)N_(4)的光催化性能进行了系统性研究。结果表明在可见光下,BiOI/K-C_(3)N_(4)复合样品对甲醛的降解率在60min内可达到81%,比未复合前有显著提高,表明样品具有良好的光催化性能。A series of BiOI/K-C_(3)N_(4)composites with different mass ratios were prepared by coprecipitation method applied BiOI and K-C_(3)N_(4)as carrier.The photocatalytic properties of BiOI/K-C_(3)N_(4)were systematically studied by means of scanning electron microscopy,UV-vis diffuse reflectance spectroscopy,X-ray diffraction and photoelectrochemical measurements.The results showed that the degradation rate of formaldehyde of BiOI/K-C_(3)N_(4)composite samples was 86% in 60min under visible light,which was significantly higher than that of non-composite samples.
