Abstract

Carbon supports are functionalized with −COOH, −OH, −NH2, surfactants, and polyelectrolytes to efficiently attach and disperse metal nanoparticles on their surface influencing the catalytic activity of fuel cell electrocatalysts. This chapter discusses different methods which have been applied for carbon support surface modifications, from chemical covalent to physical non-covalent functionalization. In the covalent method, different oxidizing agents and nitrogen-containing precursors are commonly used to anchor functional groups on carbon surface. On the other hand, in the non-covalent functionalization method different surfactants and polyelectrolytes act as capping agents and anchoring sites to help disperse and attach metal nanoparticles. With the help of surface functionalization, both electrocatalyst and fuel cell performance are improved.
