钴,氮共掺杂多孔炭用于高性能氧还原电催化剂OA北大核心CSCDCSTPCD
Co, N co-doped porous carbons as high-performance oxygen reduction electrocatalysts
钴和氮共掺杂炭催化剂(Co-NC),由于成本低廉和资源丰富而备受关注,但其低的氧还原反应(ORR)活性和对氧气的双电子(2e-)还原生成H2O2的高选择性,进一步影响了其在燃料电池中的应用.因此,Co-NC催化剂是通过在650、750和850℃下热解CoCl2和壳聚糖的混合物(用ZnCl2预处理),然后用HNO3洗涤并在900℃下退火而制备.结果表明,ZnCl2有利于壳聚糖与Co2+的络合,同时也是造孔的化学活化剂.此外,退火会导致通过碳热还原锌…查看全部>>
Although the Co and N co-doped carbon catalyst (Co-NC) has attracted much attention because of its low cost and the natural abundance of the dopants, it has a low oxygen reduction reaction (ORR) activity and a high selectivity for the two-electron (2e-) reduction of oxygen to H2O2, which affects its use in fuel cells. Co-NC catalysts were prepared by the pyrolysis of a mixture of cobalt chloride and chitosan pretreated with zinc chloride at 650, 750 and 850 …查看全部>>
