【 摘 要 】

The photo catalyst Fe (OH)3/g-C3N4 was successfully prepared by a simple method. Degradation performance of BP-5R by Fe(OH)3/g-C3N4 and g-C3N4 was compared, the results showed that the removal rate of BP-5R by Fe(OH)3/g-C3N4 can reached 93.9% at 1.0h, which was 2.87 times higher than that of the pure g-C3N4. The prepared samples were characterized and analyzed using a series of characterization methods. It was found that the enhancement of photocatalytic performance was mainly due to the transfer of photoelectrons to the Fe (OH)3. At the same time, the main active species in the process of photocatalytic degradation were analyzed. The results demonstrated that the active species including h+ and •O2- are predominant role in the photocatalytic reaction.
