A high-efficiency platinum catalyst stabilized with sodium citrate for methanol oxidation is introduced in this paper, in which freshly prepared non-noble active cobalt is employed as reducer. According to X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements, the novel as-prepared nanoclusters Pt catalyst dispersed on carbon is composed of Pt nanoparticles, and the average...
A novel catalyst support was synthesized by in situ chemical oxidative polymerization of pyrrole on Vulcan XC-72 carbon in naphthalene sulfonic acid (NSA) solution containing ammonium persulfate as oxidant at room temperature. Pt nanoparticles with 3–4nm size were deposited on the prepared polypyrrole–carbon composites by chemical reduction method. Scanning electron microscopy and transmission electron...
