In this work, five novel Cd/Zn-based MOFs with different topological framework, namely {[Cd(bimb)(Hbipa)]·H₂O}_n (1), {[Cd₃(dimb)₃(bipa)₂(H₂O)₂]·2H₂O}_n (2), [Cd(bimd)(Hbipa)(H₂O)]_n (3), {[Zn(bipd)(Hbipa)]·H₂O}_n (4) and [Zn(bimb)(Hbipa)]_n (5) had been synthesized and characterized. Worth noting, Complex 1 and 2 had effective separation behaviors towards MO and MBE dyes respectively, which could reach the adsorption equilibrium within a quite short time even if there existed another kind of dye in the system. Meanwhile, Complex 3–5 showed great performance in CR adsorption. Additionally, Complex 3–5 also showed excellent photocatalytic degradation capabilities toward MB and MV dyes under UV irradiation. According to the study, these five metal-organic frameworks can be used as a kind of functional materials in the adsorption and photocatalytic degradation of organic dyes in wastewater.

在这项工作中，五个具有不同拓扑框架的新颖的基于Cd / Zn的MOF分别为{[Cd（bimb）（Hbipa）]·H ₂ O} _n （1）， {[Cd ₃（dimb）₃（bipa）₂（H ₂ O）₂ ]·2H ₂ O} _n （2），[Cd（bimd）（Hbipa）（H ₂ O）] _n （3），{[Zn（bipd）（Hbipa）]·H ₂ O } _n （4）和[Zn（bimb）（Hbipa）] _n （5）已合成并表征。值得注意的是1号和2号综合楼分别对MO和MBE染料具有有效的分离行为，即使系统中存在另一种染料也可以在很短的时间内达到吸附平衡。同时，配合物3 – 5在CR吸附方面表现出色。此外，复杂的3 - 5也表现出对UV辐射下MB和MV染料优异的光催化降解能力。根据研究，这五种金属有机骨架可作为一种功能材料，用于废水中有机染料的吸附和光催化降解。
