Abstract
•Two different Zn/Cd-based MOFs with 2-fold interpenetrating have been designed and synthesized.•The photocatalytic investigations indicate that they afford good photocatalytic capabilities in degradation of methyl violet (MV).•The possible mechanism has been proposed.
Two Zn/Cd-based meta-organic frameworks (MOFs) build by 1,3-bis(2-methylimidazolyl)propane (bmp), 1,4-benzenedicarboxy acid (1,4-H2BDC) and 1,3,5-benzenetricarboxylic acid (H3BTC), namely: [Zn2(1,4-BDC)2(bmp)•DMF] (1) and [Cd3(H2O)2(bmp)2(DMF)(BTC)2•3•5H2O•1.5DMF] (2) have been designed and synthesized. 1 exhibits a (4,6)-connected network with Schläfi point symbol {3•4•53•6}{32•42•54•66•7}. 2 displays a new 3D (3,3,4)-connected motif with {4•92}{42•82•92}2 topology. The photocatalytic investigations showed that both of them afford efficient photocatalytic capabilities in degradation of methyl violet.
The photocatalytic investigations indicate that 1 and 2 afford good photocatalytic capabilities in degradation of methyl violet (MV). The possible photocatalytic mechanisms have been discussed. [Display omitted]
