Abstract. To develop a photo-Fenton catalyst that works under mild conditions, we report the fabrication of Fe2O3 / g-C3N4 composite via a simple two-step calcination process for the degradation of phenol under room temperature, neutral solution, and simulated sunlight. The photo-Fenton catalytic degradation constant of the Fe2O3 / g-C3N4 composite is 7.07 and 7.62 times that of Fe2O3 and g-C3N4, respectively. The limited size of Fe2O3 and partial reduction of Fe3 + in the Fe2O3 / g-C3N4 composite promotes the production of · OH radical. The Z-mechanism with efficient charge separation efficiency contributes to the enhanced photo-Fenton catalytic performance.

Z-scheme Fe2O3/g-C3N4异质结具有优异的光催化性能

摘要。为了开发在温和条件下工作的光芬顿催化剂，我们报告了通过简单的两步煅烧工艺制备 Fe2O3 / g-C3N4 复合材料，用于在室温、中性溶液和模拟阳光下降解苯酚。Fe2O3/g-C3N4复合材料的光芬顿催化降解常数分别是Fe2O3和g-C3N4的7.07倍和7.62倍。Fe2O3/g-C3N4复合材料中Fe2O3的有限尺寸和Fe3+的部分还原促进了·OH自由基的产生。具有高效电荷分离效率的 Z 机制有助于增强光芬顿催化性能。
