【摘要】 用水解沉淀法在海泡石上负载BiOCl制备出BiOCl-海泡石负载材料,研究了温度、pH值和Bi(NO3)3用量对材料形貌的影响;以罗丹明B为目标降解物,探究了材料的光催化性能。结果表明,控制温度、pH值和Bi(NO3)3用量能制备出花球状BiOCl的负载材料。BiOCl球由片状BiOCl组装而成,并均匀分散在海泡石中;BiOCl球比纯BiOCl的光催化效果提高了14.29%-16.67%,且具有优异的循环稳定性。更多还原

【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)3concentration 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.更多还原
