摘要
尽管析氢反应集成催化电极的研究取得了很大进展,但高效制备具有高电流密度的高性能催化电极仍然是一个具有挑战性的问题。在这项工作中,利用液体焦耳加热,成功地在泡沫镍上原位生长了金属(Pt)-非晶氧化物(NiO)异质结构催化剂。基于电极表面的超亲水性及其优异的机械和化学稳定性,该催化电极在过电位仅为100 mV的碱性电解质中表现出优异的催化性能,达到5000 mA cm−2的电流密度,并在1000 mA cm−2的固定电流密度下保持500 h的稳定性能。进一步验证了Pt@NiO-Ni电极在碱性电解槽中的实际应用。结果表明,以NiFe层状双氢氧化物为阳极,Pt@NiO-Ni为阴极的碱性水电解槽性能优于以往报道的电解槽,在1.75 V下已达到1 a cm−2的电流密度,甚至可与某些阴离子交换膜式水电解槽相媲美。这些实验结果表明Pt@NiO-Ni电极在工业规模电流密度下具有很强的适用性。
High-Performance Hydrogen Evolution Reaction Catalytic Electrodes by Liquid Joule-Heating Growth
Despite the great progress in the research of integrated catalytic electrodes for hydrogen evolution reaction, the efficient preparation of high‐performance catalytic electrodes with high current density remains a challenging issue. In this work, a metal (Pt)‐amorphous oxide (NiO) heterostructure catalyst is successfully in situ grown on nickel foam using liquid Joule‐heating. Based on the superhydrophilic surface of the electrode and its superior mechanical and chemical stability, the catalytic electrode exhibits excellent catalytic performance in alkaline electrolytes with only 100 mV overpotential to achieve 5000 mA cm−2 current density and maintains a stable performance of 500 h under a fixed current density of 1000 mA cm−2. Further verification of the practical application of the Pt@NiO‐Ni electrode in the alkaline electrolyzer is conducted. The results show that the alkaline water electrolyzer with NiFe layered double hydroxide as the anode and Pt@NiO‐Ni as the cathode exhibits superior performance than the previously reported electrolyzers, with a current density of 1 A cm−2 already achieved at 1.75 V, which is even comparable to some anion exchange membrane water electrolyzers. These experimental results illustrate the strong applicability of Pt@NiO‐Ni electrode at industrial scale current densities.
