Research progress of coordination materials for electrocatalytic nitrogen oxides species conversion into high-value chemicals

Abstract

The pervasive utilization of fossil fuels precipitates a surge in nitrogen oxides (NOx) emissions, adversely impacting both environmental quality and human well-being. How to effectively manage these waste products is a global issue. Electrochemical NO_x reduction powered by renewable energy represents an innovative strategy for environmental remediation and synthesis of valuable nitrogen-containing chemicals. Coordination materials with flexible regulatory characteristics have emerged as promising candidates in the electro-conversion of NO_x into valuable nitrogen-containing chemicals, including inorganics (ammonia and hydroxylamine), and organic compounds (amino acids, oximes, urea, amides, and amines). This review delineates recent advancements in the utilization of coordination materials for the electrochemical conversion of NO_x into valuable nitrogenous chemicals, aiming to build a novel bridge between inorganic and organic chemistry.
