High-entropy alloys (HEAs) contain five or more main elements, and each element ranges in content from 5% to 35%. Due to the abundant selectivity of elements, excellent structural stability, and adjustable active centers, HEAs have been widely used in electrocatalysis. Designing HEA catalysts at the atomic scale can deeply describe their structural complexity and accurately reflect the relationship between HEA structure and catalytic performance. In this Review, the atomic design of HEA-based electrocatalysts is introduced and it is evaluated in terms of activity, stability, selectivity, and efficiency. Ingenuity at the atomic level can customize the atomic composition and geometric structure of HEAs, thereby enhancing the intrinsic activity of the catalytic site, creating new active sites, and improving operational stability. The Review provides insights into excellent electrocatalytic properties and guidance for the design and synthesis of advanced HEA electrocatalysts from the viewpoint of atomic fabrication.

Electrochemical water splitting is a promising technique for the production of high‐purity hydrogen. Substituting the slow anodic oxygen evolution reaction with an oxidation reaction that is thermodynamically more favorable enables the energy‐efficient production of hydrogen. Moreover, this approach facilitates the degradation of environmental pollutants and synthesis of value‐added chemicals through the rational selection of small molecules as substrates. Strategies for small‐molecule selection and electrocatalyst design are critical to electrocatalytic performance, with a focus on achieving a high current density, selectivity, Faradaic efficiency, and operational durability. This perspective discusses the key factors required for further advancement, including technoeconomic analysis, new reactor system design, meeting the requirements of industrial applications, bridging the gap between fundamental research and practical applications, and product detection and separation. This perspective aims to advance the development of hybrid water electrolysis applications.

The electrochemical alcohol oxidation reaction (AOR) is pivotal for the development of sustainable energy. The complete oxidation of alcohols has attracted extensive attention as a vital process in fuel cells. Moreover, as an alternative reaction to the oxygen evolution reaction, the selective oxidation of alcohols emerges as an effective means to lower the energy expenditure associated with electrolytic hydrogen production while yielding high‐value products. Nonprecious metal materials have been widely applied in the selective oxidation catalysis of alcohols due to their cost‐effectiveness and excellent durability. In recent years, leveraging the advantages of nonprecious metal materials in electrocatalytic AOR, researchers have delved into catalytic mechanisms and various efficient catalysts have been fabricated and evaluated. This review provides an overview of the current advancements in the electrocatalytic selective oxidation of diverse alcohols and the catalytic systems centered around nonprecious metal materials. It systematically summarizes the shared traits and distinctions in catalytic reaction characteristics across various systems, thereby laying the theoretical foundation for developing novel catalyst systems that are efficient, stable, and highly selective. This review will facilitate the utilization of nonprecious metal catalysts further toward the electrocatalytic oxidation of alcohols.
