A novel Fe₂O₃-ZrO₂ catalyst was prepared by the sol-gel method, and investigated for phenol degradation in the Fenton-like reaction under neutral pH condition. The ZrO₂ addition increased the surface areas of the catalyst. Scanning electron microscopy (SEM) showed that ZrO₂ nano-particle dispersed on the surface of Fe₂O₃. X-ray photoelectron spectroscopy (XPS) indicated that the Fe²⁺ amount increased with the increase of the Zr content on the surface. The Fe₂O₃-ZrO₂ catalyst produced hydroxyl radicals (OH) and superoxide radicals (O₂⁻/HO₂), and exhibited good catalytic performance in the reaction. Total phenol conversion and 56% TOC removal were achieved after 210 min under neutral pH at 60 °C in the heterogeneous Fenton-like reaction. In addition, the prepared Fe₂O₃-ZrO₂ catalyst had good magnetism.

通过溶胶-凝胶法制备了一种新型的Fe ₂ O ₃ -ZrO ₂催化剂，并研究了在中性pH条件下Fenton样反应中苯酚的降解。ZrO _2的添加增加了催化剂的表面积。扫描电子显微镜（SEM）显示ZrO ₂纳米颗粒分散在Fe ₂ O ₃的表面上。X射线光电子能谱（XPS）表明，Fe ^2+的含量随着表面Zr含量的增加而增加。Fe ₂ O ₃ -ZrO ₂催化剂产生羟基自由基（OH ）和超氧自由基（O₂ ^- / HO ₂），并且在反应表现出良好的催化性能。在非均相的Fenton样反应中，在60°C的中性pH下210分钟后，总酚转化率和TOC去除率达到56％。另外，制得的Fe ₂ O ₃ -ZrO ₂催化剂具有良好的磁性。
