摘要: Having a strong electron-withdrawing ability, poly(diallyldimethylammonium chloride) (PDDA) was used to create net positive charge for carbon atoms in the nanotube plane via intermolecular transfer. The resultant PDDA functionalized/adsorbed nanotubes (CNTs), either an aligned or nonaligned form, were demonstrated act as metal-free catalysts oxygen reduction reaction (ORR) fuel cells with similar performance Pt catalysts. adsorption-induced charge-transfer should provide general approach various carbon-based efficient ORR cells, and even new catalytic materials applications beyond cells.
