锌锰共掺杂铁酸铋磁性和光催化性能研究

Abstract

Abstract: Zn，Mn co-doped BiFeO3 nano-powders（BFMZO）were synthesized with sol-gel method.R3c rhombohedral to P4mm cubic phase change was observed in BiFeO3 powders with Zn and Mn doping.XPS analysis showed that Bi and Fe in BFMZO were trivalent，and Mn and Zn were tetravalent and divalent respectively.5% Mn（fraction of number of atoms） doping had no significant effect on the micro-morphology of BiFeO3.And Zn dopant made the particle size of samples increased.The saturation magnetization of BFMZO decreased with the increase of Zn dopant and the visible light absorption of BiFeO3 was enhanced.It was found that BiFeO3 with 5% Mn and 2.5% Zn（fraction of number of atoms） doping had the best photocatalytic activity.

Key words: BiFeO3, sol-gel method, photo-catalysis
