摘要
novel amorphous mixed-valent molybdenum oxide film was grown on a glassy carbon by the electrodepositing method. Its electrochemical behaviors were studied by cyclic voltammetry and amperometry. It exhibited a high stability and electrocatalytic activity for the reduction of iodate. Amperometry revealed a good linear relationship between peak current with the concentration of iodate in the range of 1 x 10(-6) and 2 x 10(-4) mol L-1 with a correlation coefficient of 0.9997 and the detection limit of 5 x 10(-7) mol L-1 (signalmoise, = 3: 1).
