Electrosynthesis And Electrochemical Mechanism Of Zn-Based Metal-Organic Frameworks

The Zn-based MOFs which choose acrylamide and acrylic acid as organic ligand were first synthesized by an effective and versatile electrochemical method. The physical and chemical properties of the complex were characterized by atomic absorption spectrometry, FTIR, TG, XRD means, the influence of synthesis time and the effect of initiator Ce4+ had also been investigated. The results show that the optimal current density and reaction time for the synthetic crystals is 0.125 A/cm(2) and 1.5 h at the temperature 25 degrees C. Under this condition, and specific surface area of prepared Zn(acrylamide-co-acrylic acid) are 273275, 267 degrees C-395 degrees C and 186.3 m(2)/g, respectively. Meanwhile, the mechanism of the electrochemical synthesis process was investigated and the reaction course was determined through electrochemical method. The anodic and the cathodic apparent transport coefficient and derived the rate controlling step in the electrochemical synthesis process had been calculated, the role of free radicals played in the electrosynthesis reaction had also been discussed. This electrosynthesis method provides a new way for the synthesis of MOFs porous materials.
