摘要

Pt-Ru microparticles have been electrodeposited by the pulse galvanostatic method onto nanofibrous polyaniline (PANI) film synthesized directly onto stainless steel (SS). The Pt-Ru/nanofibrous PANI/SS electrode has been characterized by scanning electron microscopy and energy dispersive X-ray spectroscopy. Electrocatalytical properties of the Pt-Ru/nanofibrous PANI/SS electrode have been investigated by cyclic voltammetry in 1 M CH ₃OH+0.5 M H₂SO₄ solution. The results show that the electrode exhibits a considerably high electrocatalytic activity for methanol oxidation. The effects of the ratio of Pt to Ru, deposition charge of Pt-Ru, temperature, scan rate and methanol concentration have been evaluated. The activation energy of methanol oxidation on the electrode has been found to be 22.18 kJ mol^-1.
