Abstract

High-entropy alloys (HEAs) possess unique physical and chemical properties clearly distinguishable from those of traditional alloys, making them promising candidates for various applications, including electrocatalysis. While the electrocatalytic performance of these alloys has been assessed in detail, the electrochemical stability is often assumed to be improved compared with single metals and simple alloys. Such an assumption is rarely supported by theoretical or experimental data and might be misleading for the further successful implementation of HEAs in real devices. In this review, we provide a brief overview of the current state of this research direction, identify the common pitfalls in assessing alloy stability, and discuss the need for advanced coupled experimental/computational studies directed toward understanding the partial dissolution of elements from alloys.

我们对高熵合金的电化学稳定性了解多少？

高熵合金（HEAs）具有明显区别于传统合金的独特物理和化学特性，使其在包括电催化在内的各种应用中大有可为。虽然已对这些合金的电催化性能进行了详细评估，但通常认为与单一金属和简单合金相比，它们的电化学稳定性会有所提高。这种假设很少得到理论或实验数据的支持，可能会误导 HEAs 在实际设备中的进一步成功应用。在这篇综述中，我们简要概述了这一研究方向的现状，指出了评估合金稳定性的常见误区，并讨论了为了解合金中元素的部分溶解而进行先进的耦合实验/计算研究的必要性。

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
