Seed Displacement, Epitaxial Synthesis of Rh/Pt Bimetallic Ultrathin Nanowires for Highly Selective Oxidizing Ethanol to CO2
Source abstract
Abstract
For the first time, the high-yield, branched Rh/Pt bimetallic ultrathin nanowires with nodes and stems have been synthesized by seed displacement, epitaxial growth method in aqueous solution containing Rh nanocubes seeds, K 2 PtCl 6, and poly(vinyl pyrrolidone) (PVP). The quantities of Rh nanocubes play a key role in the formation of high-yield ultrathin nanowires. The results of EDS line scanning and elemental analysis map have shown that the Rh atoms distribute discretely in the wires. The electrocatalytic properties of the Rh/Pt bimetal alloys, Rh nanocubes, and commercial Pt black toward ethanol oxidation have been investigated. The Rh/Pt ultrathin nanowires have displayed enhanced electrocatalytic performance and selectivity. The results of in situ FTIR have shown that the selectivity to the complete oxidation of ethanol to CO 2 of Rh/Pt bimetallic ultrathin nanowires is at least 2.69 times higher as compared with the commercial Pt black.
