Enhanced photocatalysis using metal-organic framework MIL-101(Fe)for crude oil degradation in oil-polluted water
利用溶剂热法合成了一种稳定的金属有机框架(MOF)MIL-101(Fe),并作为一种新型光催化剂提高了油田废水中原油的降解性能.通过对反应条件的优化,确定了以下最佳参数:暗反应时间为30 min,光反应时间为30 min,pH值为5.5,催化剂量为150mg/L,反应温度为303.15 K.在这些反应条件下,去除率达到了 94.73％.本研究是铁基MOFs在油田废水光催化降解中的应用.MIL-101(Fe)在温和的酸性条件下表现出良好的稳定性,并且可以有效地循环利用.这些发现为利用MIL-101(Fe)作为一种很有前途的工业应用材料,通过光催化降解从受油污染的水中去除原油提供了有价值的见解.
A stable metal-organic framework(MOF),MIL-101(Fe),was successfully synthesised using a solvothermal method and employed as a novel photocatalyst for degrading crude oil in oilfield wastewater.Through optimisation of reaction conditions,the following optimal parameters were determined:a dark reaction time of 30 min,a light reaction time of 30 min,a pH of 5.5,a catalyst amount of 150 mg/L,and a reaction temperature of 303.15 K.Under these reaction conditions,an impressive removal of 94.73％was achieved.This study represents the first application of Fe-based MOFs in the photocatalytic degradation of oilfield wastewater.MIL-101(Fe)notably demonstrated excellent stability under mild acid conditions and can be efficiently recycled.These findings offer valuable insights into using MIL-101(Fe)as a promising material for industrial applications in removing crude oil from oil-polluted water through photocatalytic degradation.
