Abstract

Nanoparticle-stacked porous Ni₃FeN nanosheets were synthesized through a simple nitridation reaction of the corresponding LDHs. The nanosheet is composed of stacked nanoparticles with more active sites exposed for electrocatalytic reactions. Thus, it exhibited excellent oxygen evolution reaction performance having an extremely low overpotential of 223 mV at 10 mA/cm² and hydrogen evolution reaction property with a very low overpotential of 45 mV at 10 mA/cm². This electrocatalyst as bifunctional electrodes is used to overall water splitting in alkaline media, showing a high performance with 10 mA/cm² at a cell voltage of 1.495 V.

纳米颗粒堆叠多孔氮化镍铁纳米片:一种高效的双功能电催化剂

通过简单的氮化反应，制备了纳米颗粒堆积的多孔Ni3FeN纳米片。纳米片由具有更多活性位点的纳米颗粒堆叠而成，暴露在电催化反应中。因此，它具有优异的析氧反应性能，在10 mA/cm2时过电位极低，为223 mV;在10 mA/cm2时过电位极低，为45 mV。该电催化剂作为双功能电极用于碱性介质中水的全面分解，在电池电压为1.495 V时表现出10 mA/cm2的优异性能。
