Herein, we describe an in-situ hybridization of Nickel Selenide (Ni₃Se₂) with a Nickel Foam (NF) current collector as an efficient, ultra-durable electrode for the continuous alkaline water electrolysis. Earth abundant, cost effective, non-precious self-made Ni₃Se₂/NF electrode delivers an oxygen evolution reaction (OER) overpotential value of 315mV at a current density of 100mAcm⁻² (versus a reversible hydrogen electrode) in aqueous electrolyte of 1M KOH. On a static current density of 100mAcm⁻², Ni₃Se₂/NF electrode shows a good OER stability over 285h with very small potential loss of 5.5% in alkaline electrolyte. Accordingly, the alkaline water electrolyzer constructed with Ni₃Se₂/NF (anode) and NiCo₂S₄/NF (cathode), it requires 1.58V to deliver 10mAcm⁻² current density, with 500h continuous operation in 1M KOH. In addition, we demonstrate that the light-driven water splitting using solar panel, it can be a promising approach to facilitate true independence from electricity in H₂ fuel economy. Overall, this methodology is one of the appropriate energy efficient ways to reduce the cost of water splitting devices, as it may simplify the diverse process and equipment.

硒化镍负载在泡沫镍上，作为碱性水电解的高效，耐用的非贵金属电催化剂

在这里，我们描述了硒化镍（Ni ₃ Se ₂）与镍泡沫（NF）集电器的原位杂交，作为连续碱性水电解的高效，超耐用电极。在100mAcm ^-2的电流密度（相对于可逆的氢电极）中，地球上充裕的，具有成本效益的，非贵重的自制Ni ₃ Se ₂ / NF电极可在315 mV的电流密度下产生315mV的析氧反应（OER）超电势值。 1M KOH。在100mAcm ^-2的静态电流密度下，Ni ₃ Se ₂/ NF电极在285小时内显示出良好的OER稳定性，在碱性电解液中的电势损失很小，为5.5％。因此，由Ni ₃ Se ₂ / NF（阳极）和NiCo ₂ S ₄ / NF（阴极）构成的碱性水电解槽需要1.58V来输送10mAcm ^-2的电流密度，并在1M KOH中连续运行500h。此外，我们证明了使用太阳能电池板进行光驱动的水分解，在促进H ₂燃料经济性中实现真正的电力独立性方面可能是一种很有前途的方法。总的来说，这种方法是降低分水装置成本的合适的节能方式之一，因为它可以简化各种工艺和设备。
