Abstract

We investigated the catalytic activity of Pt-incorporated CuO electrodes for thin-film fuel cells. The electron microscopy and X-ray diffraction results show the formation of Pt nanoparticles embedded within an amorphous CuO matrix (Pt-CuO nanocomposite). The Pt-CuO nanocomposite electrode gives a much higher current density than a Pt only electrode at an accelerating voltage of 0.67 V in a mixture of 2.0 M CH₃OH and 0.5 M H₂SO₄ solutions. The enhanced catalytic activity of the nanocomposite electrode is attributed to the increased active surface area, due to the formation of Pt nanoparticles, and the amorphous CuO supporting matrix.
