Abstract

Sepiolite/flower-like BiOCl nanocomposites as photocatalyst have been successfully prepared by hydrolysis precipitation method. And the influence of temperature, pH and Bi(NO₃)₃ concentration on the unique morphology of the nanocomposites was investigated. Moreover, the photocatalytic activity of these nanocomposites was examined for the degradation of rhodamine B. The results show that the flower-like BiOCl is uniformly dispersed on the sepiolite and this nanocomposites exhibit a photocatalytic efficiency of 14.29%-16.67% higher than that of pure BiOCl nanosheets for the degradation of rhodamine B, and the catalyst has an excellent cycling stability.

Key words: inorganic nonmetallic materials BiOCl sepiolite photocatalysis flower-like
