电催化剂是可再生能源技术和其他重要工业过程的关键。贵金属和金属氧化物是目前应用最广泛的电催化催化剂。然而，金属基催化剂往往存在成本高、选择性低、耐久性差、杂质中毒和燃料交叉效应以及对环境的不利影响等缺点。因此，碳基无金属催化剂作为先进的能量转换和储存的电催化剂受到了越来越多的关注。最近，在开发低成本、高效的碳基无金属催化剂方面取得了巨大的进展，用于可再生能源技术和其他技术。在这里，提供了一个简洁，但全面和关键的，在碳基无金属催化剂领域的最新进展综述。简要介绍了可再生能源转化和储存中涉及的各种反应，包括氧还原反应、析氢反应、析氧反应、二氧化碳还原反应、氮还原反应和双功能/多功能电催化，以及面临的挑战和机遇。
Electrocatalysts are key for renewable energy technologies and other important industrial processes. Currently, noble metals and metal oxides are the most widely used catalysts for electrocatalysis. However, metal‐based catalysts often suffer from multiple disadvantages, including high cost, low selectivity, poor durability, impurity poisoning and fuel crossover effects, and detrimental effects on the environment. Therefore, carbon‐based metal‐free catalysts have received increasing interest as promising electrocatalysts for advanced energy conversion and storage. Recently, tremendous progress has been achieved in the development of low‐cost, efficient carbon‐based metal‐free catalysts for renewable energy technologies and beyond. Here, a concise, but comprehensive and critical, review of recent advances in the field of carbon‐based metal‐free catalysts is provided. A brief overview of various reactions involved in renewable energy conversion and storage, including the oxygen reduction reaction, hydrogen evolution reaction, oxygen evolution reaction, carbon dioxide reduction reaction, nitrogen reduction reaction, and bifunctional/multifunctional electrocatalysis, along with some challenges and opportunities, is presented.
