Abstract
Hydrogen energy is the cleanest energy at present because its combustion product and no carbon emission. Electrolysis of water to produce hydrogen is generally considered to be the most promising method to produce hydrogen in large quantities. But electrolysis of water to produce hydrogen is without the use of a catalyst. Manganese dioxide is an efficient and green catalyst. MnO2 dioxide-polyaniline electrode was prepared by CV method and CV/CA method respectively. The properties of dioxide-polyaniline were studied with the linear sweep cyclic voltammetry test, electrochemical impedance test and tafel slope test, and the results were compared with those of MnO2 electrode. It was found the MnO2 dioxide-polyaniline electrode properties were outstanding. It was further showed that performance of manganese dioxide-polyaniline electrode was superior by preparation of CV/CA with the testes of XPS and SEM and stability test.
