Abstract
A novel composite catalysts of Pt nanorods and nanostructure<>PtCo, PtNi and PtMo alloys onto a glassy carbon electrode (GCE)
modified with nanostructured NiCo alloy are successfully electrosynthesized
for the electrocatalytic oxidation of methanol. The
morphology, chemical composition, and phase structure for the
electrodeposited catalysts are examined using scanning electron
microscope (SEM), energy dispersive X-ray spectroscopy (EDX),
and X-ray diffraction (XRD), respectively. The electrocatalytic
properties of the catalysts are investigated by cyclic voltammetric
(CV) and current-time methods. It is discovered that the
electrodeposited nano flowered NiCo alloy substrate has a great
effect on the electrocatalytic properties of the electrodeposited
catalysts. The effect of electrodeposition time for NiCo alloy is
studied. Also, the effects of the type of electrodeposition method,
pH, temperature, and concentration for the electrodeposition bath
for Pt, PtCo, PtNi and PtMo alloys on the electrocatalytic properties
of the catalysts are well studied. Furthermore, the effect of
temperature and concentration of methanol solution on MOR are
