A PLATINIUM CATALYST COATED BY GOLD NANOPARTICLE AND A METHOD FOR PREPARATION THEREOF

摘要

PURPOSE: A manufacturing method and platinum catalyst thereof are provided to coat gold on platinum catalyst by using a thermal evaporation deposition method. CONSTITUTION: A platinum is deposited on an oxide tantalum substrate at the thickness of 1~2mm by using a thermal evaporation deposition method. When the platinum is grown up at the thickness less than 1nm, the catalyst activation is degraded. Aurum is deposited on the platinum deposit at the thickness of 0.05~0.2nm by using the thermal evaporation deposition method. The efficiency of aurum-platinum catalyst is improved by coating the platinum.
