Low-Temperature Electrooxidation Catalysts for Methane Conversion
This article reviews the challenges and recent advancements in the utilization of methane (CH4) resources via low-temperature electrochemical oxidation (CH4OR) for producing value-added chemicals. Conventional indirect pathways, including methane reforming, are energy-intensive and operate under harsh conditions. In contrast, thermal catalytic partial oxidation frequently results in over-oxidation, thereby limiting its practical applications. In contrast, electrochemical CH4OR represents a promising alternative, facilitating efficient methane conversion under mild conditions, compatible with renewable energy sources, and providing advantages in product separation and transport. This review explores the mechanistic aspects of C—H bond activation during CH4OR, encompassing both direct and radical-mediated indirect pathways.
