以三乙烯四胺（TETA）为原料，在乙醇中螯合Fe和Co，然后在Ar气氛下热解，制备了一种非贵金属FeCoTETA/C催化剂，用于质子交换膜燃料电池（PEMFC）的氧还原反应（ORR）。该催化剂已被其特征在于与各种物理化学技术以及电化学分析和单电池性能测量。结果表明，碳基体上存在纳米金属间化合物FeCo颗粒和多种类型的N和O物种。与CoTETA/C催化剂相比，该催化剂具有更好的电催化活性，H2 O2含量约为10%，电子转移数约为3.8。在500 mV电压下，以该催化剂为阴极的质子交换膜燃料电池的最大功率密度为256 mWcm − 2，电流密度为514 mAcm − 2。
A promising non-precious metal FeCoTETA/C catalyst has been easily synthesized, by chelating Fe and Co with triethylenetetramine (TETA) in ethanol followed by pyrolyzing in an Ar atmosphere, as electrocatalyst for oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). The catalyst has been characterized with various physicochemical techniques as well as electrochemical analysis and single cell performance measurement. The results showed that nano-intermetallic FeCo particles and several types of N and O species are present on carbon matrix. The catalyst delivers better electrocatalytic activity toward ORR compared with CoTETA/C catalyst, the %H2O2is about 10% with an electron-transfer number of around 3.8. The PEMFC with this catalyst in cathode reaches a maximum power density of 256mWcm−2and has a current density of 514mAcm−2at 500mV.
