Abstract

The electrocatalytic properties of multi-metal materials are predominantly influenced by electronic and geometric effects related to surface and sub-surface atoms. A comprehensive understanding of these effects and their complex interplay is paramount for the efficient development of high-performance catalysts. Along with compositionally complex solid solutions (CCSS), often called high-entropy alloys (HEAs), high-entropy intermetallic compounds (HEIMCs) are an emerging class of materials with distinctive properties originating from both high-entropy alloys and intermetallic compounds. The ordered intermetallic structure is beneficial for identifying structure–property correlations of catalytic surfaces. This minireview provides a summary of the current knowledge of high entropy intermetallic compounds and their role in catalysis, with a particular focus on the key tunable parameters essential for achieving high-performance materials.

高熵金属间化合物:电催化结构-性能相关性和材料设计原理的发现平台
多金属材料的电催化特性主要受到与表面和次表面原子有关的电子和几何效应的影响。全面了解这些效应及其复杂的相互作用对于高效开发高性能催化剂至关重要。高熵金属间化合物(HEIMC)与成分复杂固溶体(CCSS)(通常称为高熵合金(HEA))一样,是一类新兴的材料,具有源于高熵合金和金属间化合物的独特性能。有序的金属间结构有利于确定催化表面的结构-性能相关性。这篇微型综述概述了高熵金属间化合物的现有知识及其在催化中的作用,尤其侧重于实现高性能材料所必需的关键可调参数。

期刊介绍: The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
