Abstract
Official abstract text for this publication.
The present invention relates to an electroconductive tungsten oxide catalyst carrying a platinum dendrite and to a method for manufacturing same, and more particularly, to a method for manufacturing an electroconductive tungsten oxide carrying a platinum nanodendrite applicable as an anode catalyst having a strong resistance to carbon monoxide poisoning in a direct methanol fuel cell. The platinum nanodendrite-electroconductive tungsten oxide nanowire catalyst according to the present invention illustrates remarkably improved resistance to carbon monoxide poisoning when compared with a common platinum nanoparticle carbon catalyst, and so, may be used as a highly efficient DMFC anode catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A catalyst, comprising electroconductive tungsten oxide nanowires supported with methanol oxidation active particles, wherein the tungsten oxide nanowires are a bundle of nanowires having a thickness of 1˜5 nm, and the methanol oxidation active particles include platinum nanodendrite particles having a size of 1-100 nm. 2. The catalyst of claim 1 , wherein the tungsten oxide is WO 2 or W 18 O 49 . 3. The catalyst of claim 1 , wherein the methanol oxidation active particle includes a platinum nanoparticle. 4. The catalyst of claim 1 , wherein the methanol oxidation active particles are all platinum nanodendrite particles. 5. The catalyst of claim 4 , wherein the platinum nanodendrite particles have a size of 1˜100 nm.
