Synthesis, structure, adsorption and electrochemical properties of the new two-dimensional cobalt coordination polymer based on bifunctional ligand
A novel two-dimensional coordination polymer {[Co(Htia)2(C2H5OH)2]·H2O}n(1) (H2tia = 5-(1H-1,2,4-triazol-1-yl)isophthalic acid, C10N3O4H7) was successfully synthesized by a solvothermal method using H2tia containing –COOH and –N bifunctional groups as ligands and transition metal Co as the central ion. 1 was analyzed by XRD, IR, UV and TG. Single-crystal X-ray diffraction analysis shows that Co2+ ions in 1 are the hexagonal distorted octahedral geometry. Neighboring Co2+ ions form a two-dimensional grid using the Htia ligand as the rigid skeleton. The adjacent 2D layers interact through hydrogen bonds to build a three-dimensional supramolecular crystalline material. Based on the laminar structure of 1, we investigated the adsorption capacity of 1 on two cationic dyes, crystalline violet and Janus green B. The results show that 1 has a certain adsorption capacity and the maximum adsorption amount of the dyes can reach as high as 56 and 176 mg g−1, respectively. The electrochemical experiment shows that 1 has good electrocatalytic activity in the electrolyte solution of 0.01 M KOH not only for the oxidation of H2O2, but also for the oxidation of ascorbic acid.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
