Platinum-based Alloy Catalyst

Platinum (Pt)-based alloys, such as iron, nickel, cobalt, and ruthenium, used to enhance the catalytic performance of platinum for direct methanol fuel cell (DMFC) and methanol oxidation reaction (MOR) performance. When used as catalysts these materials can improve stability and better electrocatalytic performance of platinum in DMFC. Different from traditional platinum catalysts that often produce sintering—a process where particles of platinum migrate and form a solid mass that reduces the specific surface area, causing the catalytic activity to drop in efficiency—this solution can mitigate sintering and reduce chemical instability.
