Abstract

With the increasing global demand for sustainable energy and environmental solutions, the development of efficient, cost-effective, and eco-friendly electrocatalysts has become a key area of research. Microorganisms, with their distinctive microstructures, abundant functional groups, and diverse metabolic activities, offer innovative pathways for the green synthesis of electrocatalysts. This review first systematically summarizes microbial-derived electrocatalysts by using microorganisms (bacteria, fungi, viruses) as templates and metabolites, e.g., extracellular polymers, bacterial cellulose as mediates, and their applications in various representative electrocatalytic reactions, including hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reaction. We then particularly focus on the application of microbial-derived electrocatalysts in CO2 reduction reaction. Microorganisms not only serve as structural templates to impart high surface areas and ordered pores to catalysts but also facilitate the introduction of active sites through metabolic processes, significantly enhancing catalytic efficiency toward the optimization of reduction products. Finally, the current challenges as well as future optimization strategies are proposed in the field of microbial-derived electrocatalysts. This work offers a guideline for the design of microbial-mediated catalytic materials, advancing new strategies toward achieving carbon neutrality.

微生物衍生电催化剂:结构和二氧化碳减排应用
随着全球对可持续能源和环境解决方案的需求不断增长,开发高效、经济、环保的电催化剂已成为一个重要的研究领域。微生物以其独特的微观结构、丰富的官能团和多样的代谢活动,为电催化剂的绿色合成提供了创新途径。本文首先系统综述了以微生物(细菌、真菌、病毒)为模板物和代谢物(如胞外聚合物、细菌纤维素等)为介质的微生物衍生电催化剂及其在析氢反应、析氧反应、氧还原反应等具有代表性的电催化反应中的应用。然后,我们特别关注微生物衍生的电催化剂在CO2还原反应中的应用。微生物不仅作为结构模板赋予催化剂高表面积和有序孔隙,而且通过代谢过程促进活性位点的引入,显著提高催化效率,优化还原产物。最后,提出了微生物电催化剂领域目前面临的挑战和未来的优化策略。这项工作为微生物介导的催化材料的设计提供了指导,推进了实现碳中和的新策略。
