Perspective on water electrolysis for ozone production: electrocatalyst design and development

Abstract

Electrocatalytic ozone production (EOP) is a new, environmentally friendly, safe and cost-efficient ozone production technology. The slow kinetics and poor stability of conventional catalysts in the EOP process limit its wide application. Consequently, the development and design of novel EOP catalysts are crucial. There have been few reviews on various types of EOP catalysts. Therefore, this paper reviews recent advances on EOP catalysts, categorized by material types. Additionally, the mechanism of EOP is discussed in depth. Finally, we propose constructive implications for future EOP system development. This paper aims to provide an in-depth analysis of the EOP process, summarize and discuss advances in EOP materials, and establish a reliable foundation for future EOP development.
