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150 mg/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.
