Abstract

Metal-organic framework aerogels (MOAs) embedded with CdS (CdS/MOA(Cr)) synthesized a facile one-pot solvothermal method have a larger surface area than pristine MOA(Cr) and the post-synthesized composite. CdS/MOA(Cr) exhibited 5 times enhancement in the photocatalytic activity than that of pure CdS for Cr(vi) reduction under visible light without adding any sacrificial agent, due to the larger surface area and photosensitazation of MOA(Cr).

摘要

通过简便的一锅溶剂热法合成的嵌入硫化镉的金属有机框架气凝胶（CdS/MOA(Cr)）比原始的MOA(Cr)和后合成的复合材料具有更大的表面积。由于MOA(Cr)具有更大的表面积和光敏化作用，在不添加任何牺牲剂的情况下，CdS/MOA(Cr)在可见光下对Cr(Ⅵ)还原的光催化活性比纯硫化镉提高了5倍。
