摘    要:抗坏血酸为燃烧剂,燃烧法制备铁酸镍复合氧化物。XRD表征分析确定硝酸铁和硝酸镍的最佳物质 的量比,紫外-可见光谱仪分析得到铁酸镍复合氧化物的吸光性能,电镜分析出复合物的形貌。以亚甲基蓝(0.01 g/L,100mL)为降解目标,铁酸镍复合氧化物为催化剂,双氧水为氧化剂进行复合物的光催化研究。结果表明,催化 剂用量、酸度、双氧水用量、光催化时间等条件对光催化都有着重要影响。光催化最佳实验条件为催化剂质量 20mg、pH=6、双氧水体积为6mL。实验结果表明,硝酸镍、硝酸铁和抗坏血酸物质的量比为1∶2∶1时,复合氧化 物在紫外和可见光下均有光催化效果;硝酸镍、硝酸铁和抗坏血酸物质的量比为2∶1∶1和1∶3∶1时,复合氧化物 在紫外光下有光催化效果。

Abstract:In this paper, ascorbic acid as combustion agent, composite oxides of nickel ferrite were prepared by combustion method. The optimal molar ratio of ferric nitrate to nickel nitrate was determined by XRD. The UV absorbance properties of composite were analyzed by UV spectra. The morphology of composites was characterized by scanning electron microscopy. The photocatalytic properties were studied using methylene blue as the degradation substrate and composite as catalyst. The experiment showed important effect of amount of catalyst, the pH value of the solution, the amount of hydrogen peroxide and irradiation time of the photocatalyst. The optimal photocatalytic condition is: dose of catalyst 20 mg, pH at 6, and hydrogen peroxide 6 mL. The results indicate that the nickel ferrite with molar ratio of nickel nitrate, ferric nitrateand ascorbic acid of 1:2:1 is photocatalytic effective under UV and visible light. Moreover, the nickel ferrite with molar ratio of nickel nitrate, ferric nitrateand ascorbic acid of 2:1:1 and 1:3:1 are photocatalytic effective under UV light.
Keywords:Nickel ferrite  Photocatalysis  Combustion
