Abstract
- • The recent advancements in NORR on parameters, experimental systems, mechanism, and catalysts are summarized as a guidance for further investigations. • The NORR electrocatalysts are classified into metals and alloys, metal compounds, and non-metal materials to facilitate the understanding of various catalysts. • The strategies for improving the NORR activity are summerized to help the design of electrocatalysts for NORR. • The challenges and perspectives of NORR were proposed for future works. Fossil fuel combustion results in significant NO x emissions, which are harmful to the environment and human health. The reasonable and effective treatment of NO x pollution is an urgent requirement. The electrocatalytic reduction of nitric oxide (NORR) to ammonia is an emerging method that can convert the NO pollutant into an important industrial product under ambient conditions, exhibiting great advantages over the severe reaction conditions of selective catalytic reduction (SCR) and Haber-Bosch processes of NH 3 synthesis, therefore, attracting the great interest of researchers. In the last few years, lots of materials for NORR have been developed based on theoretical, computational, or experimental studies. However, further breakthroughs in the catalytic activity, selectivity, and Faraday efficiency of NORR electrocatalysts are required to address the limitations in practical applications. To help future research on NORR in both theoretical and experimental directions, we summarized the recent progress in the development of NORR electrocatalysts, classifying them into metals and alloys, metal compounds, and non-metal materials according to their nature. The mechanisms or reaction pathways of NORR are also discussed. Furthermore, the experimental parameters and devices for NORR are introduced to help with experimental studies in the future. The research directions and perspectives on the further development of NORR electrocatalysts are illustrated. This review summarizes the recent advancements in NORR on parameters, experimental, mechanism, and catalysts, illustrating the types of catalysts, and the strategies for improving activity.
