Electrospun nanofiber membrane (ENM) shows great advantage and potential in wastewater treatment due to its unique properties. However, exploring a green and efficient ENM for remediation of complex wastewater, such as simultaneous containing oils, dyes and heavy metal ion, remains challenging. In this work, a cellulose-based photocatalytic ENM, is constructed for this purpose. The hybrid ENM is prepared via electrospinning deacetylated cellulose acetate/polyvinyl pyrrolidone (CeP) nanofibers as skeleton cores and in-situ synthesis of beta hydroxyl oxidize iron decorated iron-based MOF (β-FeOOH@MIL-100(Fe)) heterojunctions as photocatalytic sheaths. The core-sheath structured ENM has ultrahigh MIL-100(Fe) loading (78 wt%), large surface areas (1105 m²/g) and well-dispersed β-FeOOH nanorods. Thanks to these porous and hydrophilic MIL-100(Fe), along with a robust photocatalysis-Fenton synergy from β-FeOOH@MIL-100(Fe), the as-prepared ENM shows outstanding performances with simultaneous high removal efficiency for oils (99.5 %), dyes (99.4 %) and chromium ion (Cr(VI)) (99.7 %). Additionally, the photocatalytic ENM can achieve a long-term reuse owing to its inherent self-cleaning function.

电纺纳米纤维膜（ENM）由于其独特的特性在废水处理中显示出巨大的优势和潜力。然而，探索一种绿色高效的ENM来补救复杂的废水，例如同时含油，染料和重金属离子的废水，仍然具有挑战性。在这项工作中，为此目的构建了基于纤维素的光催化ENM。杂化ENM是通过静电纺去乙酰乙酸纤维素/聚乙烯吡咯烷酮（CeP）纳米纤维作为骨架核，并原位合成β羟基氧化铁修饰的铁基MOF（β-FeOOH@ MIL-100（Fe））异质结以光催化制备的鞘。芯鞘结构的ENM具有超高的MIL-100（Fe）负载（78 wt％），较大的表面积（1105 m ²/ g）和分散良好的β-FeOOH纳米棒。得益于这些多孔且亲水的MIL-100（Fe），以及来自β-FeOOH@ MIL-100（Fe）的强大的光催化-芬顿协同作用，所制得的ENM表现出出色的性能，同时对油脂的去除效率很高（99.5 ％），染料（99.4％）和铬离子（Cr（VI））（99.7％）。另外，由于其固有的自清洁功能，光催化ENM可以实现长期重复使用。
