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

聚电解质功能化碳纳米管作为高效的无金属氧还原电催化剂

聚（二烯丙基二甲基氯化铵）（PDDA）具有很强的吸电子能力，用于通过分子间电荷转移为纳米管碳平面中的碳原子产生净正电荷。所得的 PDDA 功能化/吸附的碳纳米管 (CNT)，无论是排列的还是非排列的，都被证明可作为燃料电池中氧还原反应 (ORR) 的无金属催化剂，其性能与 Pt 催化剂相似。吸附诱导的分子间电荷转移应该为用于燃料电池中氧还原的各种碳基高效无金属 ORR 催化剂，甚至用于燃料电池以外应用的新催化材料提供通用方法。
