Abstract:

一种直接甲醇燃料电池阴极非贵金属催化剂的制备方法属于燃料电池催化剂领域。现有的催化剂一般为贵金属,价格比较贵且易中毒。该催化剂活性组分为过渡金属氮化物,载体为Vulcan XC-72活性炭粉,其中活性组分中过渡金属氮化物的质量百分含量为1-6%。该方法为将过渡金属大环化合物、VulcanXC-72活性炭粉溶于有机溶剂中,超声30-60分钟;在溶剂中过渡金属大环化合物与Vulcan XC-72活性炭粉的质量比为1∶9-1∶1;常温下搅拌蒸干,60-80℃干燥,得到粉末,装入密闭容器,通入氨气,氨气的流量为0.5-3l/min,控制热处理的温度为600-1000℃,热处理时间为0.5-10h,自然降温得到催化剂。碳载铂催化剂的面积比活性为1.5mA/cm2;本发明的碳载氮化物催化剂,则达到了3.1mA/cm2相当于前者的2倍。该方法流程简单,过程易于控制。
