中文摘要:

      采用化学共沉淀法合成Fe_0.6Cr_0.4/Bi₇MnO_12.5复合纳米材料,用透射电子显微镜(TEM)、X射线粉末衍射分析(ⅪD)、红外光谱(FTIR)等手段对材料进行表征,用Na2CO3溶液浸渍复合纳米晶作为催化剂,对蓝色染料进行光催化降解探讨.

英文摘要:

      Fe_0.6Cr_0.4/Bi₇MnO_12.5 composite nanoparticles were prepared by chemical precipitation method and the materials were characterized by XRD TEM and FTIR. The resulting composite nanoparticles were impregnated with the solutions of Na₂CO₃ and K₂CO₃ and used to promote the photocatalytic degradation of blue dyestuffs. It has been found that the composite nanoparticles have an average size of 24.0 nm. The nanoparticles impregnated with the solutions of Na₂CO₃ and K₂CO₃ speed up the photocatalytic degradation of various blue dyestuffs greatly and thus can be used for the wastewater treatment containing the blue dyestuffs.
