• Nickel phosphate nanoparticles
• VSB-5
• CPE modified electrodes
• Methanol oxidation
• Alkaline medium

Carbon paste electrodes were modified by nickel phosphate nanoparticles and nickel phosphate Versailles Santa Barbara-5 molecular sieves. Then, transition metal ions of Ni(II) were incorporated to the nickel phosphate by immersion of the modified electrode in a 0.1-M nickel chloride solution. The electrochemical behaviors of the modified electrodes were studied using cyclic voltammetry. These modified electrodes were used as anode for the electrocatalytic oxidation of methanol in alkaline medium. The influence of some parameters such as different molecular sieves, scan rate of potential, and methanol concentration was investigated on the anodic peak height of the methanol oxidation. The best result was obtained by nickel phosphate nanoparticles.
