Electrocatalytic nitrate reduction on bimetallic Palladium-Copper Nanowires: Key surface structure for selective dinitrogen formation

Iron‐Based Nanocatalysts for Electrochemical Nitrate Reduction

“…Based on environmental concerns, most studies in the published literature prefer to obtain N 2 as the final product, which is nontoxic and harmless and can be directly emitted into the atmosphere. [57,[133][134][135][136][137][138] According to the "breakpoint chlorination" theory combined with the mechanism diagram analysis, ClOcan react with NH 4…”

Progress and prospects of electrochemical reduction of nitrate to restore the nitrogen cycle

“…The incorporation of secondary promoter metals (Cu, Sn, In) into noble metals offers a viable approach to enhance reaction rates and reduce costs. [66][67][68][69] Lim et al 69 employed underpotential deposition to synthesize Pd nanocubes with controlled Cu surface coverage (Fig. 4b).…”

Recent developments and prospects for engineering first-row transition metal-based catalysts for electrocatalytic NOx− reduction to ammonia

“…The Fe-based catalysts exhibit decent nitrate reduction activity, but the catalysts still suffer from the limitations of inferior long-term robustness and poor kinetic durability in the practical catalytic process. 20 The recent exploitation of chainmail-protected catalysts has offered innovative insights into the design of high-efficiency and robust Fe-based catalysts. Fe nanoparticles suffer from poor durability due to their greater susceptibility to leaching and oxidation during the electrocatalytic process.…”

“…However, for direct electrocatalytic reduction or advanced collection of NO x − from wastewater, it is difficult to escape from the effects of unknown NO x − concentration, other ions and pH of the solution. 20,21 Time-consuming and labor-intensive wastewater pretreatment is required due to the numerous unknown factors of wastewater, which hinder the realization of electrocatalytic NH 3 production.…”
