摘要
通过调节反应原料铋铁物质的量比,采用水热法制备了软铋矿材料Bi25FeO40,通过XRD、TEM等对其物相和形貌进行了表征,分析了反应机理;并通过罗丹明B降解实验,研究了其催化性能。结果表明,当反应原料铋铁物质的量比为(6~12)∶1时,可以得到纯相软铋矿材料Bi25FeO40,其具有良好的催化性能。
By adjusting the molar ratio of Bi-Fe in reactants,we prepared sillenite bismuth ferrite Bi25FeO40 by a hydrothermal method,and characterized their structures and morphologies by XRD and TEM.Moreover,we analyzed the reaction mechanism,and studied their catalytic performances through the degradation of Rhodamine B(RhB)by peroxymonosulfate(PMS).The results indicate that sillenite bismuth ferrite Bi25FeO40 with pure phase exhibits excellent catalytic performance when the molar ratio of Bi-Fe in reactants is(6-12)∶1.
