چکیده انگلیسی
Metal-Organic Frameworks (MOFs) can serve as precursors to a range of useful materials including porous catalysts and supercapacitors. The electrochemical properties of the ZIF-67 framework were investigated in aqueous electrolytes under neutral and basic pH conditions in the presence of different anions. The redox transformations resulted in both crystalline powders and thin films deposited on the working electrodes. In the latter case, catalytic oxidation of water was observed during the electrochemical measurements due to the formation of Co3O4 films. ZIF-67 was found to be susceptible to ligand substitution of 2-methylimidazolate by hydroxide and phosphate anions in the electrolytes.
