Abstract
In this communication, we report that Ni–Co–S film electrochemically deposited on Cu foam (Ni–Co–S/CF) behaves as a bifunctional catalyst for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) with good durability in strongly basic electrolyte. This 3D electrode behaves high activity of 10 mA cm−2 at overpotential of 140 mV for HER and 100 mA cm−2 at overpotential of 363 mV for OER in 1.0 M KOH. Furthermore, using Ni–Co–S/CF as both anode and cathode can afford 10 mA cm−2 at cell voltage of 1.67 V toward overall water splitting in alkaline solution.
在本文中，我们报道了电化学沉积在泡沫铜上的Ni-Co-S薄膜(Ni-Co-S /CF)在强碱性电解质中作为析氢反应(HER)和析氧反应(OER)的双功能催化剂，具有良好的耐久性。该3D电极在HER过电位140 mV时具有10 mA cm−2的高活性，在1.0 M KOH下OER过电位363 mV时具有100 mA cm−2的高活性。此外，在1.67 V电池电压下，Ni-Co-S /CF作为阳极和阴极可以在碱性溶液中产生10 mA cm−2的整体水分解。
期刊介绍：
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
