Abstract

The effect of vanadium on the properties of the electrode of molybdenum nitride has been studied by using XRD?SEM and cyclic voltammetry.Modified molybdenum nitride was made as follow:films were coated by dipping titanium sheet in the solution containing different composition of molybdenum oxide,ammonium vanadate,ammonia,glycol and oxalic acid,and coated films are reacted with free ammonia.The results show that the specific capacitance of modified electrode was considerably increased and the operation voltage was broadened with the addition of ammonium vanadate in the dipping solution.The mechanism of these effects generated is the formation of new phase VOMoO 4 in the electrode of molybdenum nitride,the partly amorphous phase formation of molybdenum nitride,and the change of the microstructure of the modified film.The optimum molar ratio of vanadium and molybdenum in the dipping solution was 35∶65.
