PLATIN CATALYST WITH POROEST CARBON DEFINED ON AND SURROUNDING THE PLATIN CRYSTALS AND PROCEDURE FOR THE PREPARATION OF THIS

摘要

The rate of platinum recrystallization of a platinum supported on carbon catalyst is reduced by depositing porous carbon on and around the supported platinum crystallites. The catalyst can subsequently be heated in an inert atmosphere or vacuum at a high temperature. A catalyst with an improved performance in electrochemical cells can be obtained.
