Al you need: Dealloying of Al from mother alloy Al₈₅Ni_xCo_15−x (x=5, 7.5, 10) synergistically promotes bifunctional electrocatalytic activities for oxygen reduction and evolution reactions (ORR/OER) as well as rechargeable zinc-air battery performance. Density functional theory results verify that Al doping can change the rate-determining step and significantly reduce the energy barrier of ORR/OER.

用于双功能氧电催化和可充电锌空气电池的脱合金衍生多孔尖晶石氧化物：通过遗传掺杂促进活性

您需要的铝：从母合金 Al ₈₅ Ni _x Co _{15− x} ( x =5, 7.5, 10) 中脱合金铝可协同促进氧还原和析出反应 (ORR/OER) 以及可充电锌空气的双功能电催化活性电池性能。密度泛函理论结果证实，Al掺杂可以改变速率决定步骤，显着降低ORR/OER的能垒。
