| Abstract: | The cathodic polarization curves on electrodeposited nickel lanthanum phosphorus alloy and nickel electrode in 1 mol.L\+\{-1\} potassium hydroxide solution were measured. It is showed that the rate of hydrogen evolution on the Ni La P alloy was ten times more than that of nickel electrode and that the hydrogen evolution potential on the cathode of Ni La P alloy moved positively compared with nickel cathode, which is about 200～300 mV for the Ni La P alloy at i\-c=100 150A·cm\+\{-2\}. The Ni La P alloy was provided with high catalytic activity of hydrogen evolution that can reduce the both voltage and energy loss during electrolysis of sodium chloride. |
