摘　　要：以含羟基的羧酸配体和六水合硝酸锌为原料,制得锌金属有机骨架(Zn-MOF-M).测定了Zn-MOF-M光催化还原六价铬的性能,考察了溶液酸碱性及空穴捕捉剂对催化性能的影响.研究了Zn-MOF-M可见光条件下同时去除水中六价铬和染料性能,表明光催化过程中存在协同效应,六价铬还原和染料降解的效率均有所提高.Zinc metal organic framework(Zn-MOF-M)was prepared from carboxylic acid ligand containing hydroxyl group and zinc nitrate hexahydrate.The photocatalytic activity of reduction of hexavalent chromium by Zn-MOF-M was determined,and the effects of solution acidity and hole scavenger on the catalytic performance were investigated.The simultaneous removal of hexavalent chromium and dyes from water by Zn-MOF-M under visible light was studied.The results showed that there was a synergistic effect in the photocatalytic process,and the efficiency of hexavalent chromium reduction and dye degradation were improved.
