摘要：以SBA-15为硬模板,Salen-Co为单一前驱物,采用固相研磨法合成了Co-N共掺杂石墨化的有序介孔碳材料(Co-N-C)。结果表明,实验所得到的Co-N-C-800在碱性介质中显示出了卓越的ORR的电催化活性,并呈现出优于Pt/C催化剂的抗甲醇性和稳定性。最重要的是,固相研磨法为有序介孔氧还原催化剂的制备提供了一种简便、省时、价格低廉的方法。
Ordered mesoporous Co-N co-doped graphitic carbon materials(Co-N-C)have been successfully prepared using Co-salen as a single precursor via a simple and cost-effective solid-state grinding method templated by SBA-15.The resulted Co-N-C-800 shows remarkable ORR electrocatalytic activity in an alkaline medium,and exhibits a methanol-tolerance and stability superior to Pt/C catalyst.The last but not the least,solid-state grinding method provides a facile,time-saving and inexpensive way for the synthesis of ordered mesoporous ORR catalysts.
