Abstract

Abstract: A new Pt nanocatalyst was synthesized by chemical reduction of K₂PtCl₄ by ascorbic acid in the presence of a non-ionic surfactant Brij-35 (CH₃(CH₂)₁₀CH₂(OCH₂CH₂)₂₃OH) in aqueous solution at room temperature. The obtained Pt nanocatalyst was characterized by transmission electron microscopy, energy-dispersive X-ray spectroscopy (EDX), X-ray powder diffraction, thermogravimetry (TG), and cyclic voltammetry (CV). The uniform Pt nanocatalyst possesses a globular dendritic morphology with a mean diameter of 36.9 nm. The branches of the globular dendrites are 2-4 nm in diameter and 4–6 nm in length. A simple purification method with multiple water washing was developed to remove Brij-35 and other by-products from the surface of Pt nanocatalyst. TG, EDX, and CV results show that the surface of Pt nanocatalyst after purification is as clean as that of commercial Pt black (fuel cell grade, 99.9%). Compared with commercial Pt black, Pt nanocatalyst demonstrates a higher electrochemical active surface area and significantly improved electrocatalytic activity to oxygen reduction and methanol oxidation.

Key words: globular dendritic structure, electrocatalytic activity, surfactant, platinum nanocatalyst, oxygen reduction, methanol oxidation
