In this work,the electrochemical behaviors of hydrazine at Ag electrode in the room temperature ionic liquid,BmimPF6,were studied by cyclic voltammetry. Results suggested that Ag electrode showed a good catalytic activity towards hydrazine oxidation. The catalytic peak current showed a good linear relationship with the hydrazine concentration in the range of 0 ~ 3. 4 mmol/L. The rate-determining step of the electrocatalytic reaction involved one electron transfer form hydrazine molecule to Ag + ion.
