Abstract

Utilizing efficient and eco-friendly electrochemical techniques for the synthesis of valuable chemicals represents an optimal strategy for enhancing energy utilization. Electrochemical ozone production (EOP), recognized for its cleanliness and adaptability, emerges as a promising energy conversion technology for the synthesis of high-value chemicals. However, the selection of anode materials poses a significant challenge to the widespread commercial deployment of EOP, and a thorough investigation into this area is crucial for improving both the performance and durability. In this review, we delve into the fundamental principle of ozone generation, explore the advantages and constraints associated with various EOP systems, and discuss how the utilization of advanced membrane electrode assembly (MEA) electrolysis cells can sustain an overall efficiency of 20 % or higher. This review offers objective evaluations of various anode materials and summarizes recent advancements in EOP, highlighting laboratory-measured current efficiencies that surpass 50 %. Lastly, this review delineates the myriad challenges encountered within the current EOP research and proposes potential avenues for future development, all in an effort to furnish indispensable insights for the industrial implementation of EOP.

高效电化学臭氧阳极材料的现状与展望

利用高效、环保的电化学技术合成有价化学品是提高能源利用的最佳策略。电化学臭氧生产（EOP）因其清洁性和适应性而被认为是一种有前途的高价值化学品合成的能量转换技术。然而，阳极材料的选择对EOP的广泛商业应用构成了重大挑战，对这一领域的深入研究对于提高性能和耐用性至关重要。在这篇综述中，我们深入研究了臭氧产生的基本原理，探讨了各种EOP系统的优势和限制，并讨论了如何利用先进的膜电极组件（MEA）电解电池来维持20%或更高的总效率。这篇综述提供了各种阳极材料的客观评价，并总结了EOP的最新进展，重点介绍了实验室测量的电流效率超过50%。最后，本文概述了当前EOP研究中遇到的无数挑战，并提出了未来发展的潜在途径，所有这些都是为了为EOP的工业实施提供不可或缺的见解。
