摘要
通过溶剂热法制备了UiO-66-NH_(2)/g-C_(3)N_(4)催化剂,以甲基橙(MO)染料溶液为模拟污染物,研究可见光照射下UiO-66-NH_(2)/g-C_(3)N_(4)光催化活性和循环使用稳定性。结果表明:UiO-66-NH_(2)均匀地负载在层状g-C_(3)N_(4)表面,UiO-66-NH_(2)与g-C_(3)N_(4)形成Ⅱ型异质结,抑制了光生电子-空穴的复合;当催化剂质量浓度为1.25 g/L时,其对MO的光催化降解率达到了95.6%,催化剂循环使用5次后其对MO的光催化降解率仍达到了85.2%。
UiO-66-NH_(2)/g-C_(3)N_(4) catalyst is prepared by solvothermal method.The photocatalytic activity and recycling stability of UiO-66-NH_(2)/g-C_(3)N_(4) under visible light irradiation are studied by using Methyl Orange(MO)as a simulated pollutant.The results show that UiO-66-NH_(2) is uniformly loaded on the surface of layered g-C_(3)N_(4),and UiO-66-NH_(2) and g-C_(3)N_(4) form type II heterojunction,which inhibits the recombination of photogenerated electrons and holes.When the catalyst dosage is 1.25 g/L,the photocatalytic degradation rate of MO reaches 95.6%.After five cycles of UiO-66-NH_(2)/g-C_(3)N_(4) catalyst,the photocatalytic degradation rate of MO still reaches 85.2%.
