摘要

在具有良好导电性的石墨纤维毡（GF）上直接生长了纳米级的 FeWO4/BiVO4 异质结，从而构建了类似于太阳能光-芬顿废水处理系统的 FeWO4/BiVO4 @GF。研究了该系统对酚类废水中 COD 的去除效果以及协同提高废水处理效率的机理。水热法制备的 FeWO4/BiVO4 异质结表现出更高的光电转换效率和太阳光利用率，从而赋予 FeWO4/BiVO4 优异的类似太阳-芬顿反应活性。在 GF 上添加 FeWO4/BiVO4 纳米异质结有助于增加 Fenton 试剂与废水的接触面积，促进 FeWO4/BiVO4 异质结上的电子转移，实现 Fenton 试剂的回收和再利用。在太阳光照射下，FeWO4/BiVO4 @GF/H2O2 系统对酚类废水中 COD 的去除率超过 92%，即使在五个循环之后，该系统仍然表现出极佳的运行稳定性。FeWO4/BiVO4@GF通过加速光生电子/空穴的分离和传输，提高活性物种的浓度，促进了Fe(III)/Fe(II)的转化和循环，从而激发了类似太阳能光-芬顿的优异活性。

Nanoscale FeWO₄/BiVO₄ heterojunctions were directly grown on the graphite fiber felt (GF) with good conductivity to construct a FeWO₄/BiVO₄ @GF solar photo-Fenton like wastewater treatment system. The removal effect of COD from phenolic wastewater and the mechanism of synergistic improvement of wastewater treatment efficiency by this system were investigated. The FeWO₄/BiVO₄ heterojunction prepared by hydrothermal method exhibited higher photoelectric conversion efficiency and solar light utilization rate, thus endowing FeWO₄/BiVO₄ with excellent solar-Fenton like reaction activity.The photo-Fenton activity can be maintained well even within the pH range of 2–8. Loading FeWO₄/BiVO₄ nano-heterojunction on GF helped to increase the contact area between Fenton reagents and wastewater, facilitate the electron transfer on the FeWO₄/BiVO₄ heterojunction and enable the recovery and reuse of the Fenton reagents.Under solar light radiation, the COD removal efficiency of FeWO₄/BiVO₄ @GF/H₂O₂ system in phenolic wastewater was more than 92%. Even after five cycles, the system still exhibited excellent operation stability. FeWO₄/BiVO₄@GF promoted the conversion and cycling of Fe(III)/Fe(II) by accelerating the separation and transport of photogenerated electrons/holes and increasing the concentration of active species, thereby stimulating excellent solar photo-Fenton like activity.The results are significance to the development of green and efficient photo-Fenton process for advanced treatment of industrial wastewater.
