“…[37][38][39][40][41] During the process of water splitting, relatively high energy (at least 1.6 V) beyond the theoretical energy input (1.23 V) is demanded for driving the overall electrocatalytic reactions. 42 To tackle this issue, thermodynamically more favorable oxidation reactions have been explored to replace OER, such as alcohol oxidation, 43,44 urea oxidation, [45][46][47] biomass oxidation, 48,49 and 5-(hydroxymethyl)furfural (HMF) oxidation. 50,51 In this context, plastic oxidation is also emerging as an attractive alternative to OER with the advantages of less energy input and waste utilization.…”

With large quantities and natural resistance to degradation, plastic waste raises growing environmental concerns in the world. To achieve the upcycling of plastic waste into value‐added products, the electrocatalytic‐driven process is emerging as an attractive option due to the mild operation conditions, high reaction selectivity, and low carbon emission. Herein, this review provides a comprehensive overview of the upgrading of plastic waste via electrocatalysis. Specifically, key electrooxidation processes including the target products, intermediates and reaction pathways in the plastic electro‐reforming process are discussed. Subsequently, advanced electrochemical systems, including the integration of anodic plastic monomer oxidation and value‐added cathodic reduction and photo‐involved electrolysis processes, are summarized. The design strategies of electrocatalysts with enhanced activity are highlighted and catalytic mechanisms in the electrocatalytic oxidation of plastic waste are elucidated. To promote the electrochemistry‐driven sustainable upcycling of plastic waste, challenges and opportunities are further put forward.

The development of high‐performance electrocatalysts for energy conversion reactions is crucial for advancing global energy sustainability. The design of catalysts based on their electronic properties (e.g., work function) has gained significant attention recently. Although numerous reviews on electrocatalysis have been provided, no such reports on work function‐guided electrocatalyst design are available. Herein, we provide a comprehensive summary of the latest advancements in work function‐guided electrocatalyst design for diverse electrochemical energy applications. This includes the development of work function‐based catalytic activity descriptors, and the design of both monolithic and heterostructural catalysts. The measurement of work function is first discussed and the applications of work function‐based catalytic activity descriptors for various reactions are fully analyzed. Subsequently, the work function‐regulated material‐electrolyte interfacial electron transfer (IET) is employed for monolithic catalyst design and methods for regulating the work function and optimizing the catalytic performance of catalysts are discussed. In addition, key strategies for tuning the work function‐governed material‐material IET in heterostructural catalyst design are examined. Finally, perspectives on work function determination, work function‐based activity descriptors, and catalyst design are put forward to guide future research. This work paves the way to the work function‐guided rational design of efficient electrocatalysts for sustainable energy applications.This article is protected by copyright. All rights reserved

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.
