PREPARATION OF THE CATALYSTS PLATINUM SYSTEM

摘要

PURPOSE: A method for manufacturing platinum-based catalyst is provided to increase the activity of the catalyst and to reduce the using amount of the catalyst by increasing the active area of platinum in the catalyst. CONSTITUTION: A method for manufacturing platinum-based catalyst includes the following: metal salt is dissolved in a solvent; a carbon support is added into the dissolved solution; fine platinum particles are formed in the solution by using epoxide; the fine platinum particles are washed and dried; and the dried product is passivated. The metal salt is chloroplatinic acid. The solvent is water or alcohol. The support is selected from a group including alumina, silica, zeolite, titania, niobia, and the mixture of the same. The epoxide is propylene oxide or buthylene oxide.
