摘要 在氮气(N2)保护下,采用常压溶剂热法制备出花状前驱体铁醇盐,之后在空气中500℃热处理得到α-三氧化二铁(α-Fe2O3)微球。并对α-Fe2O3进行表征和分析,研究了其对甲基橙的光催化降解性能。结果表明:制得的α-Fe2O3微球具有较大的比表面积,为66.92m2/g,还具有弱铁磁性特征,饱和磁化强度为2.11emu/g,剩磁为0.55emu/g,矫顽力为210.91Oe,有利于使用磁铁吸附分离。在甲基橙溶液为10mg/L,多孔花状α-Fe2O3微球的浓度为0.5g/L,紫外灯照射3h条件下,多孔花状α-Fe2O3微球对甲基橙的降解率最高达到60.05%。采用磁铁分离并经过6次重复使用后,对甲基橙的降解率为50.85%,具有较好的降解性能。

Abstract: Flower-like iron alkoxide was synthesized by a solvothermal method under nitrogen(N2) flow,and porous flower-like α-ferric oxide(α-Fe2O3) particles were obtained with a subsequent heat treatment at 500℃ in air.The products were characterized and analyzed.The degradation experiment on methyl orange was also carried out.The results shown that the α-Fe2O3 had a large specific surface area of 66.92m2/g.And it was weak ferromagnetic.The saturation magnetization value(Ms),remanence value(Ms) and coercivity value(Hc) were 2.11emu/g,0.55emu/g and 210.91Oe respectively.When the concentration of α-Fe2O3 microspheres was 0.5g/L and methyl orange solution was 10mg/L,it had an excellent photocatalytic rate of methyl orange,namely 60.05% after ultraviolet radiation for 3h.It can be collected simply by a magnetite and the degradation rate of methyl orange remained 50.85% after 6 cycles.
