Preparation and Electrocatalytic Performance for Methanol Oxidation of Pt-CeO2/Sodium-4-styrenesulfonate Functionalized Carbon Nanotube Composites†

doi:10.7503/cjcu20170168

Abstract

Abstract:

Carbon nanotubes(CNTs) were noncovalently modified by anionic polymer poly(sodium-4-styrenesulfonate)(PSS) to obtain PSS functionalized CNTs(PSS-CNTs), and then Ce³⁺ was assembled to CNTs surface through the electrostatic interaction between electropositive Ce³⁺ and electronegative PSS. Through the electrostatic interaction and oxidation-reduction reaction between Ce³⁺and PtC $l 4 2 -$ , CeO₂ and Pt nanoparticles were in-situ deposited on the surface of CNTs to obtain PSS-CNTs supported Pt-CeO₂ composite catalyst(Pt-CeO₂/PSS-CNTs). The structure, component and micromorphology of Pt-CeO₂/PSS-CNTs were characterized by transmission electron microscopy(TEM), X-ray diffraction(XRD), X ray photoelectron spectroscopy(XPS), energy dispersive X-ray spectroscopy(EDS) and Raman spectroscopy, respectively. The electrochemical study shows that, due to the smaller particle size, the better dispersion uniformity and stability of Pt nanoparticles in-situ deposited on the surface of PSS-CNTs compared with those on the original CNTs, and the synergetic effect between Pt and CeO₂, Pt-CeO₂/PSS-CNTs, especially Pt-CeO₂/PSS-CNTs with n_Pt/n_Ce of 2/3, exhibits higher catalytic activity and stability for methanol electrooxidation compared with Pt-CeO₂/CNTs and PtRu/C.
