| Abstract: | Effects of additives triethylene tetramine and melamine on the direct oxidation of sodium borohydride with aurum(Au) catalyst were studied by cyclic voltammetry and electrochemical impedance spectroscopy tests.More H atoms of each BH4-could oxidate at the catalytic spots due to the absorption of triethylene tetramine and melamine which reduced BH4-on electrode.The catalytic action of Au on direct oxidation of sodium borohydride was improved through adding triethylene tetramine and melamine,the optimal conce... |
