Synthesis and photocatalytic performance of a dinuclear cadmium(II)-based coordination polymer for degradation of organic pollutants in wastewater
We report the synthesis of a dinuclear cadmium (II)-based coordination polymer, {[Cd3(BTC)2(H2O)3]·1.5Beib·9H2O}n(1), via a solvothermal method using CdCl2, 1,3,5-benzenetricarboxylic acid (H3BTC), and 1,4-bis(2-ethylimidazol-1-yl)butane (Beib) in a mixed solvent of N,N-Dimethylacetamide (DMA) and distilled water. The photocatalytic efficiency of 1 was evaluated for the degradation of organic pollutants such as 2,4-dinitrophenol (DNP), 2,4,6-trinitrophenol (TNP), 3-nitrophenol (MNP), and 4-nitrotoluene (PNT) in wastewater. The complex showed remarkable photocatalytic activity, with 20 ppm DNP achieving 97.17 % degradation using 30 mg of photocatalyst 1 within 100 min. Trapping experiments confirmed superoxide radicals and h+ as the primary active species. The complex also demonstrated excellent stability and reusability across multiple cycles in various water sources.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
