Abstract

The formic acid oxidation reaction (FAOR) is a key anodic process in direct formic acid fuel cells and requires efficient electrocatalysts with high activity and resistance to catalyst poisoning. In this study, a graphitic carbon nitride (g-C₃N₄)-modified glassy carbon electrode (g-C₃N₄/GC) was fabricated and evaluated for FAOR in acidic media. The electrocatalytic performance of the modified electrode wa [...]
