Electrocatalytic Nitrate Reduction for Sustainable Ammonia Production

Abstract

nology (joint degree) in 2017. She completed a master's degree in chemistry with a specialization in energy and sustainability at Leiden University in 2020, working on the development of catalysts for the oxygen reduction reaction, and was a visiting student at the Institute of Chemical Research of Catalonia (ICIQ). Since 2020, she is a PhD candidate in the Catalysis and Surface Chemistry group of Leiden University. Her current research focuses on electrocatalysis for the sustainable production of hydrogen peroxide.

Recent advances in metal-mediated nitrogen oxyanion reduction using reductively borylated and silylated N-heterocycles

“…Examples in the literature of electrophiles for nitrate deoxygenation include low valent metals, [24][25][26][27] carbon monoxide, 28 and protons. 29,30 The use of protons for nitrate reduction is coupled with electron transfer, often in an aqueous solution. Heterogenous systems that facilitate nitrogen oxyanion reduction boast efficiency, but often at the expense of mechanistic understanding and selectivity.…”

Efficient Nitrogen Fixation to Ammonia through Integration of Plasma Oxidation with Electrocatalytic Reduction

“…[11] Thep roduction of ammonia via electrochemical NO x À reduction reaction (eNO x RR) however is less developed, suffering from issues including low selectivity to NH 3 ,high overpotentials and poor stability. [12] Cu-based nanomaterials are conventionally used as electrocatalysts for eNO x RR [13] but require high overpotentials (ca. 1.2 V) to obtain practically acceptable yields and FEs.T his can be ascribed to the low binding affinity and nucleophilicity of NO x À on Cu surface,a nd sluggish water dissociation failing to provide sufficient protons.…”

Advances in Electrochemical Ammonia Synthesis Beyond the Use of Nitrogen Gas as a Source

“…To the best of our knowledge, previously published reviews under this topic mostly focused on the electroreduction of nitrogenous molecules with desired selectivity to harmless N 2 , which can either be returned to the atmosphere, or subsequently converted to NH 3 . However, the direct selective ammonia synthesis through NO x reduction is rarely discussed in the reviews published so far [31–35] . Besides, there were only few research articles targeting NH 3 as their desired product in NO x electroreduction [36–39] .…”

“…However, the direct selective ammonia synthesis through NO x reduction is rarely discussed in the reviews published so far. [31][32][33][34][35] Besides, there were only few research articles targeting NH 3 as their desired product in NO x electroreduction. [36][37][38][39] In this review, we focus on electrocatalytic NO x reduction toward ammonia generation, from both theoretical and experimental perspectives.…”
