摘要
NH_2-UiO-66是一类具有良好的热稳定性和化学稳定性,具有可见光响应活性的MOFs材料。为进一步提高其光催化活性,本文采用气相扩散-沉积-光还原法制备了等离子体光催化剂Ag/AgCl@NH_2-UiO-66。由于Ag/AgCl和NH_2-UiO-66之间的协同效应,该催化剂表现出优良的可见光光催化活性。在可见光照射下(λ≥420 nm),该复合材料对20 mg L~(-1)的RhB溶液降解效率14 min内即可达到98%。
In this paper,a novel visible-light responsive photocatalyst,Ag/AgCl@NH_2-UiO-66,was synthesized via vapor diffusion-photoreduction strategy.The degradation efficiency of 20 mg L~(-1) Rhodamine B can be reached to 98% within 14 min under visible-light irradiation(λ≥420 nm).
