摘要
以无定形金属有机框架(MOF)为前驱体,通过900℃热解制备Co-N共掺杂碳基氧还原反应(ORR)催化剂Co-N/C。XRD和SEM测试结果表明:Co-N/C具有典型的石墨化特征,形貌为直径350~650 nm的球形。该催化剂在0.1 mol/L KOH电解质中具有较好的ORR催化活性,起始电位为0.978 V,半波电位为0.856 V,极限电流密度为6.12 mA/cm^(2),且具有较好的抗CO和抗甲醇中毒性能,应用前景良好。
Amorphous metal organic framework(MOF)was used as precursors to prepare Co-N co-doped carbon-based oxygen reduction reaction(ORR)catalyst Co-N/C by pyrolysis at 900℃.XRD and SEM test results showed that the Co-N/C had typical graphitization characteristics,the morphology was spherical with a diameter of 350-650 nm.The catalyst showed fine ORR performance in 0.1 mol/L KOH electrolyte,the initial potential was 0.978 V,the half wave potential was 0.856 V,the limited current density was 6.12 mA/cm^(2),exhibited good anti-CO and anti-methanol poison tolerance,which had good application prospect.
