Abstract

Producing organic electro-oxidation and hydrogen evolution reactions (HER) simultaneously in an electrolytic cell is an appealing method for generating valuable chemicals at the anode while also producing H₂ at the cathode. Within this framework, the task of designing energy-saving electrocatalysts with high selectivity and stability is a considerable challenge. Carbon-based catalysts, along with their supports, have emerged as promising candidates due to their diverse sources, large specific surface area, high porosity and multidimensional characteristics. This review summarizes progress from 2012 to 2022, in the use of carbon-based catalysts and their supports for organic electrooxidation and HER. It delves into outer-sphere electrooxidation mechanisms involving molecule-mediated oxidation and oxidative radical coupling reactions, as well as inner-sphere electrooxidation mechanisms, encompassing both acidic and alkaline electrolytes. The review also explores prospective research directions within this domain, addressing various aspects such as the design of electrocatalytic materials, the study of the relationship between the structure and properties of electrocatalysts, as well as examining their potential industrial applications.

用于同时进行有机电氧化和氢气进化反应的碳基催化剂和催化剂载体综述

在电解池中同时进行有机电氧化反应和氢进化反应（HER）是一种很有吸引力的方法，既能在阳极产生有价值的化学物质，又能在阴极产生 H2。在此框架内，设计具有高选择性和稳定性的节能型电催化剂是一项相当大的挑战。碳基催化剂及其载体具有来源多样、比表面积大、孔隙率高和多维等特点，因此已成为前景广阔的候选催化剂。本综述总结了从 2012 年到 2022 年在使用碳基催化剂及其支持物进行有机电氧化和 HER 方面取得的进展。综述深入探讨了涉及分子介导氧化和氧化自由基偶联反应的外层电氧化机制，以及包括酸性和碱性电解质在内的内层电氧化机制。综述还探讨了这一领域的前瞻性研究方向，涉及电催化材料的设计、电催化剂结构与性能之间关系的研究以及其潜在的工业应用等各个方面。

期刊介绍： New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
