In this work, five novel Cd/Zn-based MOFs with different topological framework, namely {[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) 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. [Display omitted] • Produce novel Cd/Zn -based MOFs that possess novel 3D structure. • Selectively absorb specific aromatic dyes in a mixed aqueous system. • Exhibit efficient photocatalytic degradation abilities towards MB/MV in aqueous solution.
