“…Defect engineering pertains to the deliberate introduction of imperfections or aberrations into the catalyst structure. These flaws may contain edges, voids, or dislocations that can act as catalytic reaction sites [46]. Adding these flaws increases the reactivity and surface area, improving the electrocatalytic effectiveness of reactions such as the reduction of nitrate (NO 3 − ) to NH 3 .…”

The electrocatalytic production of ammonia has garnered considerable interest as a potentially sustainable technology for ammonia synthesis. Recently, non-metallic-doped materials have emerged as promising electrochemical catalysts for this purpose. This paper presents a comprehensive review of the latest research on non-metallic-doped materials for electrocatalytic ammonia production. Researchers have engineered a variety of materials, doped with non-metals such as nitrogen (N), boron (B), phosphorus (P), and sulfur (S), into different forms and structures to enhance their electrocatalytic activity and selectivity. A comparison among different non-metallic dopants reveals their distinct effects on the electrocatalytic performance for ammonia production. For instance, N-doping has shown enhanced activity owing to the introduction of nitrogen vacancies (NVs) and improved charge transfer kinetics. B-doping has demonstrated improved selectivity and stability, which is attributed to the formation of active sites and the suppression of competing reactions. P-doping has exhibited increased ammonia generation rates and Faradaic efficiencies, likely due to the modification of the electronic structure and surface properties. S-doping has shown potential for enhancing electrocatalytic performance, although further investigations are needed to elucidate the underlying mechanisms. These comparisons provide valuable insights for researchers to conduct in-depth studies focusing on specific non-metallic dopants, exploring their unique properties, and optimizing their performance for electrocatalytic ammonia production. However, we consider it a priority to provide insight into the recent progress made in non-metal-doped materials and their potential for enabling long-term and efficient electrochemical ammonia production. Additionally, this paper discusses the synthetic procedures used to produce non-metal-doped materials and highlights the advantages and disadvantages of each method. It also provides an in-depth analysis of the electrochemical performance of these materials, including their Faradaic efficiencies, ammonia yield rate, and selectivity. It examines the challenges and prospects of developing non-metallic-doped materials for electrocatalytic ammonia production and suggests future research directions.

“…Several concepts for the synthesis of ammonia from atmospheric N 2 using renewable energy sources have been proposed, like (i) direct electrocatalytic reduction, 16,17 (ii) plasma-enabled synthesis, 18 and (iii) chemical looping, 19,20 as documented in reviews. 4,6,21 Electrocatalytic N 2 reduction suffers from very low yield. 22 Plasma processes have an energy cost many times higher than those of HB processes.…”

“…23 Chemical looping is facing some challenges related to mass transfer, cyclability, material volumes and cost. 21,24 An additional option for producing ammonia is to extract and convert N-sources contained in side products and waste streams from the agro-industry, contributing in this way to N-circularity. 25–27…”
