Researchers from Rice University have discovered that nitrogen-doped carbon nanotubes or modified graphene nanoribbons could potentially replace platinum for fast oxygen reduction—a crucial reaction in fuel cells that transform chemical energy into electricity.

“If arranged in a foam-like configuration, such material can approach the efficiency of platinum,” Rice graduate student Luqing Wang said in a statement. “If price is a consideration, it would certainly be competitive.”
