摘要
以FeCl_3·6H2O和NaOH作为反应物,聚乙二醇200为模板剂,水热法合成了棒状的Fe2O3纳米晶,用TEM、XRD和FI-IR对样品进行表征。TEM表征结果显示,样品的形貌随着制备条件的改变而发生变化。通过优化制备条件制得粒径均匀棒状氧化铁。采用十二烷基硫酸钠对棒状的Fe2O3进行改性,并对其氧化脱硫性能进行研究。结果表明,改性后的Fe2O3纳米棒与超声作用发生耦合效应,二者协同可有效脱除模拟油中噻吩硫化物,脱硫率可达到100%。
Using FeCl3 ·6H2O and NaOH as reactants, polyethylene glycol 200 as template agent, rodlike Fe2O3 nano- crystalline was synthesized. The samples were characterized by TEM, XRD and FI-IR. The results of TEM show that morphology of samples were changed with conditions of preparation.The synthetic conditions of nano rods were optimized. The Fe2O3 nanorods were modified by sodium lauryl sulfate and its effect of oxidative desulfurization of thiophene was studied. Experiments show that modified Fe2O3 nanorods could significantly promote the removal of thiophene in the simulated oil due to effect of coupling existed between modified Fe2O3 catalyst and ultrasonic. The desulphurization rate could reach 100%.
