| Abstract: Cobaltous complexes catalyzing the oxidation of water are meaningful to the development of clean energy and new oxidation reaction. Anew ligand of 3-((bis(pyridin-2-ylmethyl)amino)methyl)phenyl)(3,5-dimethyl-1H-pyrrol-2-yl)methanone and the cobaltous complex (Co1) were synthesized and characterized by IR, UV, NMR, ES-MS, et al. methods. The oxidation of water catalyzed by Co1 in aqueous solution was studied. Results show that the complex Co1 can catalyze the oxidation of water to release the O2 with TON of 15.38. The mechanism of water oxidation with the release of O2 was explored by CV method. Experimental results demonstrate that Co1 is a new kind of noble free molecule catalyst to the oxidation of water. |
