Carbon nitride simultaneously boosted a PtRu electrocatalyst's stability and electrocatalytic activity toward concentrated methanol

Abstract

Ruthenium dissolution is an inevitable issue for an anodic electrocatalyst in direct methanol fuel cells (DMFCs). Carbon nitride (C₃N₄) decoration derived from the carbonization of melamine simultaneously promoted a PtRu electrocatalyst's stability and electrocatalytic activity toward concentrated methanol ascribed to the additional active sites from C₃N₄.
