聚苯胺基碳催化剂：以聚苯胺为原料，通过化学聚合，然后在氨水存在下热解，制备了低成本的掺氮碳纳米材料作为燃料电池阴极电催化剂。该催化剂表现出高活性，起始电位与商业铂催化剂相当，还原电流高于商用铂催化剂。
PANI-BASED CARBON CAT: A low-cost nitrogen-doped carbon nanomaterial from polyaniline as fuel cell cathode electrocatalyst is prepared by chemical polymerization of aniline monomers, followed by pyrolysis in the presence of ammonia. The catalyst demonstrates high activity, with an onset potential comparable to, and a reduction current higher than, a commercial platinum catalyst.
