A nanoscale tungsten nitride/nitrogen-doped carbon (WN/NC) catalyst was synthesized through a facile route, and it exhibited efficient catalytic performance for hydrogen and oxygen recombination at room temperature with an average catalytic velocity of 140 μmol h g and long catalytic life of 954 660 s without decay in the catalytic performance. With the WN/NC catalyst, a nickel-iron battery could be sealed and maintenance-free, and it also exhibited low cost; thus, the nickel-iron battery can be used for large-scale energy storage systems in rural/remote areas.
通过一种简便的方法合成了一种纳米级氮化钨/氮掺杂碳（WN/NC）催化剂，该催化剂在室温下对氢氧复合表现出高效的催化性能，平均催化速度为140 μmol h g ，催化寿命长达954660秒，催化性能无衰减。使用WN/NC催化剂，镍铁电池可以密封且无需维护，成本也较低；因此，镍铁电池可用于农村/偏远地区的大规模储能系统。
