EXTREMELY POROUS Pt-CeO2 STRUCTURES GROWN ON CARBON FILMS FOR FUEL CELLS APPLICATIONS

摘要

Platinum is a versatile element in catalysis that efficiently mediates a multitude of chemical reactions. Unfortunately, Pt is rare noble metal and its high price exceeding that of gold limits large- scale applications. Therefore, there is the major driving force in catalysis research to reduce the content of platinum in catalysts and use it efficiently as possible, or to replace the noble metal by others less expensive materials.
