双微乳液法制备掺杂Fe3+的纳米TiO2及其光催化性能OA北大核心CSTPCD
Fe3+ Doped TiO2 Nano-particles Prepared by Double Microemulsion Method and Photocatalytic Activity
为了研究双微乳液法在制备纳米级光催化剂的应用,以TiCl4和NH3· H2O为原料,采用十六烷基三甲基溴化铵-正丁醇-环己烷-水微乳体系制备Fe3+掺杂纳米TiO2,对粉末的晶体结构进行X射线衍射表征,并以其对p-甲酚的降解考察其光催化活性.结果表明,在较小的掺杂量时,Fe3+掺杂量的提高可以提高TiO2的光催化活性,进一步提高掺杂量将引起光催化活性的降低；掺杂Fe3+可导致纳米TiO2的粒径减小；Fe3+的半径较小以及Fe2O3的熔点较低均有利…查看全部>>
In order to research the application of double microemulsion method for preparing nano-sized catalysts, Fe3+doped TiO2 nano-particles were obtained in microemulsion of CTAB-butanol-cyclohexane-H2O with TiC14 and NH3·H2O asraw meterials.The crystal structure of Fe3+doped TiOz nano-particles was characterized by XRD and the degradation of p -cresol was investigated for the photocatalytic activity of them. The results show that (he photocatalytic activity incre…查看全部>>
