摘要：

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 photoFenton 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 center dot OH radical. The Z-mechanism with efficient charge separation efficiency contributes to the enhanced photo-Fenton catalytic performance. (C) 2020 Society of Photo-Optical Instrumentation Engineers (SPIE)
