Electro-oxidation of methanol on mesoporous nickel phosphate modified GCE

► Mesoporous nickel phosphate NiPO-2 was used to modify GCE electrode. ► NiPO-2/GCE was active and stable for the electro-oxidation of methanol. ► The electro-oxidation of methanol on NiPO-2/GCE was a single diffusion-controlled process. ► NiPO-2/GCE showed potentials in developing sensors for determination of methanol.
