The conversion of NO3‐‐to‐NH3 by electrolysis is an appealing approach for wastewater treatment; however, such a process is hindered by the lack of efficient catalysts. Herein, taking the nanoporous Al11Ce3 intermetallic phase as an example, its electrocatalytic NO3‐ reduction reaction capability is first demonstrated. Benefiting from the unique structural feature, optimized intermediates adsorption and formation behavior, and restrained hydrogen evolution, the catalyst shows a remarkable electrochemical performance with a peak faradaic efficiency of 91% and yield rate of 4.35 mg h–1 mgcat–1, along with robust activity over 30 h. Further, a Zn–NO3‐ battery by using Al11Ce3 as the cathode was designed, which gives a maximal power density of 8.5 mW cm–2 and a corresponding NH3 yield rate of 1.97 mg h–1 mgcat–1.

RR) under mild conditions is still challenging. Enzyme is well-known for its high efficiency and specificity under mild conditions. Electroenzymatic cascade systems combining the advantages of electrocatalysis andThe electrochemical nitrite reduction reaction provides an alternative approach to offer sustainable ammonia source routes for repairing imbalances in the global nitrogen cycle. In this work, electrocatalysis is combined with enzymatic catalysis to provide an efficient and clean process for recoverable ammonia production. NO 2 − is reduced to NH 3 by electroenzymatic cascade reduction reaction on a bioconjugate, in which 1-butyl-3-methylimidazolium bromide (IL BMB ) modified chloroperoxidase (CPO) is fixed on polyethyleneimine (PEI) modified multi-walled carbon nanotubes (MWCNT) to from bioconjugate (CPO-IL BMB /MWCNT-PEI). 15 N and 14 N isotope labeling reveal that the NH 3 species is derived from NO 2 − reduction. Density functional theory calculations identify that the Fe II species in heme center of CPO serve as the key active site for NO 2 − reduction. The amino groups derived from MWCNT-PEI not only serve as a bridge to covalently immobilize CPO but also enrich the NO 2 − ion at electrode/solution interface through electrostatic interactions. The low energy barrier of NO 2 − reduction and low adsorption free energy of the intermediate result in high Faradaic efficiency (96.4%), NH 3 yield (112.7 mg h −1 mg CPO −1 ), and high selectivity in pH 5.0 solution. The highly efficient electroenzymatic reaction ensurespromising applications in the conversion of NO 2 − to NH 3 .

Electrochemical Nitrate Reduction: Ammonia Synthesis and the Beyond

Natural nitrogen cycle has been severely disrupted by anthropogenic activities. The overuse of N‐containing fertilizers induces the increase of nitrate level in surface and ground waters, and substantial emission of nitrogen oxides causes heavy air pollution. Nitrogen gas, as the main component of air, has been used for mass ammonia production for over a century, providing enough nutrition for agriculture to support world population increase. In the last decade, researchers have made great efforts to develop ammonia processes under ambient conditions to combat the intensive energy consumption and high carbon emission associated with the Haber‐Bosch process. Among different techniques, electrochemical nitrate reduction reaction (NO3RR) can achieve nitrate removal and ammonia generation simultaneously using renewable electricity as the power, and there is an exponential growth of studies in this research direction. Here we provide a timely and comprehensive review on the important progresses of electrochemical NO3RR, covering the rational design of electrocatalysts, emerging C‐N coupling reactions, and advanced energy conversion and storage systems. Moreover, future perspectives are proposed to accelerate the industrialized NH3 production and green synthesis of chemicals, leading to a sustainable nitrogen cycle via prosperous N‐based electrochemistry.This article is protected by copyright.
