通过水热法一步合成了一种｛001｝晶面暴露的片状 BiOCl 和石墨烯（GS）复合材料。获得的 BiOCl/ GS 光催化剂用 X 射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和紫外-可见（UV - Vis）漫反射光谱表征。所制备的 BiOCl/ GS 光催化剂表现出紫外和可见光下（λ＞400 nm）增强光催化降解甲基橙（MO）的性能。光催化活性的增强是因为｛001｝面的 BiOCl/ GS 能有效地抑制电荷复合、氧空位和光生电子转移效率高。%A series of composites of the high photoactivity of{001}facets exposed BiOCl and graphene sheets(GS)were synthesized via a one - step hydrothermal reaction. The obtained BiOCl/ GS photocatalysts were characterized by X - ray diffraction(XRD),scanning electron microscopy(SEM),transmission elec-tron microscopy(TEM),Ultraviolet - visible(UV - Vis)diffuse reflectance spectroscopy. The as - pre-pared BiOCl/ GS photocatalyst showed enhanced photocatalytic activity for the degradation of methyl orange (MO)under UV and visible light(λ > 400 nm). The enhanced photocatalytic activity could be attributed to oxygen vacancies of the{001}facets of BiOCl/ GS and the high migration efficiency of photo - induced e-lectrons,which could suppress the charge recombination effectively.
