PLATINIUM-PALLADIUM COMPOSITE CATALYST HAVING A NEW STRUCTURE AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A platinum-palladium composite catalyst and a method for manufacturing the same are provided to improve the activity of the catalyst by including uniformly dispersed platinum components and palladium components. CONSTITUTION: Platinum components and palladium components are uniformly dispersed in the particles of a platinum-palladium composite catalyst. A plurality of needle shaped branches with anisotropic property is coagulated. The catalyst is in the form of a star or a sea urchin. The branches are grown from the center parts of the particles. The sizes of the particles are in a range between 5 and 50nm. A method for manufacturing the catalyst includes a process in which a platinum component containing material and a palladium component containing material are co-reduced in ionic liquid. The platinum component containing material is potassium platonic chloride. The palladium component containing material is sodium chloropalladate.
