Cu-Based Catalysts for Electrocatalytic Nitrate Reduction
in recent years,electrocatalytic nitrate reduction(ENitRR)has attracted considerable attention in the synthesis of ammonia at ambient conditions.Compared to the traditional Haber-Bosch process for ammonia synthesis,ENitRR offers lower energy consumption and milder reaction conditions.the design and optimization of ENitRR electrocatalysts are crucial for nitrate deoxygenation and hydrogenation.copper-based catalytic materials have been widely studied due to their unique structure,low cost,and excellent performance,making them highly promising electrocatalysts through various morphology and electronic structure modulation strategies.This article summarizes various effective design strategies using copper-based electrocatalysts as a typical example to enhance the ammonia production rate and conversion efficiency in ENitRR.It also introduces the reaction mechanism and the relationship between structural changes in Cu-based electrocatalysts and their performance.These strategies include morphology modulation,alloy engineering,lattice phase tuning,single-atom structures,as well as copper compound construction and composites with other materials.Finally,challenges faced by copper-based electrocatalysts are discussed along with future research directions that should be focused on in order to provide reference for researchers engaged in nitrate treatment in aqueous systems。
