摘要Carbon supported Pt(Pt/C) catalyst was prepared using Pt(NO3)(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 Pt2+, forming the complex. However, EDTA would combine to Pt2+ through the electrostatic interaction, leading to that the Pt particles obtained are not easy to be aggregated. Thus, when Pt(NO3)(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.
