Beschreibung
Zusammenfassung:	The present invention relates to a preparation method of Pt/CNT electrode catalyst carried by carbon nano tube. It is characterized by that the carbon nano tube can be used as carrier, a light-catalyzed in-situ chemical reduction precipitation method is utilized, and the ethylalcohol (or formaldehyde) can be used as reduction agent, and the chloroplatinic acid can be reduced and deposited on the activated carbon nano tube so as to obtain the invented Pt/CNTs catalyst with high activity for proton, exchange membrane fuel cell direct methyl alcohol fuel cell. As compared with existent electrodecatalyst said invention features large specific surface area, high porosity, good dispersion property and low platinum use level.
