摘要:
以四氨基钴酞菁(Cobalt tetraaminophthalocyanine,CoPc(NH2)4)为结构单元,4,4′联苯二甲醛为连接基团,通过希夫碱反应在炭黑表面原位生长得到CoCOFs/CB前驱体,然后高温热解得到高效氧还原活性的过渡金属/氮/碳(MNC)催化剂:CoCOFs/CBX(X=600、700、800 ℃)。使用透射电子显微镜、傅里叶红外光谱和X射线光电子能谱等对样品的微观形貌、官能团结构以及表面成分等进行表征。测试表明:CoCOFs/CB700催化剂存在暴露的CoN/C、吡啶氮以及石墨氮的活性位点,有效提高了氧还原活性和稳定性。CoCOFs/CB700催化剂的半波电位达到0841 V,极限电流密度为596 mA/cm2,电子转移数为378~396,HO2-产率为25%~141%。这表明CoCOFs/CB700催化剂具有接近20% Pt/C的氧还原活性,氧还原途径为接近4电子的反应途径,且稳定性和抗甲醇性能均优于20% Pt/C。这说明CoCOFs/CB 700催化剂在燃料电池和金属空气电池领域具有潜在的应用前景
