中文摘要	carbon supported pt(pt/c) catalyst was prepared using pt(no(3))(2) as the precursor and ethylenediaminetetraacetic acid(edta) as additive. the catalyst was characterized by x-ray diffraction(xrd) spectroscopy, transmission electron microscopy(tem), ultraviolet visible(uv-vis) absorption spectroscopy, fourier transform infrared(ftir) spectroscopy and electrochemical methods. the measurement results indicate that edta could not coordinate with pt(2+), forming the complex. however, edta would combine to pt(2+) through the electrostatic interaction, leading to that the pt particles obtained are not easy to be aggregated. thus, when pt(no(3))(2) was used as the-precursor, edta can also effectively reduce the average size of the pt particles and improve the dispersion degree. the average size of the pt particles in the pt/c catalyst obtained is only 3 nm and the dispersion of the pt particles is uniform. therefore, the pt/c catalyst obtained has the excellent electrocatalytic activity and stability for methanol oxidation.
