Dopamine-induced Pt and N-doped carbon@silica hybrids as high-performance anode catalysts for polymer electrolyte membrane fuel cells†
Abstract
We report a simple and bio-friendly method to synthesize platinum (Pt) and nitrogen (N)-doped carbon@silica using polydopamine (PDA). This silica-based composite permits greater humidifying capacity to sufficiently hydrate membrane electrode assemblies (MEAs), thus improving electrochemical properties for polymer electrolyte membrane fuel cells (PEMFC).
