Tandem catalysis in electrocatalytic nitrate reduction: Unlocking efficiency and mechanism
Summary
This review covers recent progress in designing catalysts that can efficiently convert harmful nitrate pollution in water into harmless nitrogen gas using electricity. While not directly about microplastics, the technology is relevant because nitrate and microplastic contamination often co-occur in polluted water, and better water treatment methods could address multiple pollutants. The research advances environmentally friendly approaches to cleaning up contaminated water supplies.
Abstract The electrochemical nitrate reduction reaction (NO 3 RR) holds promise for ecofriendly nitrate removal. However, the challenge of achieving high selectivity and efficiency in electrocatalyst systems still significantly hampers the mechanism understanding and the large‐scale application. Tandem catalysts, comprising multiple catalytic components working synergistically, offer promising potential for improving the efficiency and selectivity of the NO 3 RR. This review highlights recent progress in designing tandem catalysts for electrochemical NO 3 RR, including the noble metal‐related system, transition metal electrocatalysts, and pulsed electrocatalysis strategies. Specifically, the optimization of active sites, interface engineering, synergistic effects between catalyst components, various in situ technologies, and theory simulations are discussed in detail. Challenges and opportunities in the development of tandem catalysts for scaling up electrochemical NO 3 RR are further discussed, such as stability, durability, and reaction mechanisms. By outlining possible solutions for future tandem catalyst design, this review aims to open avenues for efficient nitrate reduction and comprehensive insights into the mechanisms for energy sustainability and environmental safety.
