Abstract The electrochemical C‐N coupling process, facilitating the production of organic nitrogen substances (such as urea, methylamine, formamide, and ethylamine) via simultaneous reduction carbon dioxide (CO 2 ) small nitrogen‐based substances, stands at forefront advancing neutrality artificial cycle. This method has garnered substantial interest due to its potential economic environmental benefits. Although considerable progress been achieved in this emerging field, it still faces challenges, including slow reactant adsorption, competing side reactions, complex multi‐step pathways, resulting low yields selectivity. Strategically designing developing low‐cost exceptionally performant catalysts is crucial for cost‐effective precise C─N bonding. article offers an in‐depth review electrosynthesis valuable compounds ambient conditions from earth‐abundant resources/wastes, such CO nitrogenous molecules (nitrogen: N , nitrite: NO − nitrate: 3 ammonia: NH etc.), bond formation especially using carbon‐based catalysts. relevant mechanisms, design principles advanced electrocatalysts, impact different electrolyser designs are discussed, along with present obstacles upcoming prospects dynamic field.

Predicting electrocatalytic urea synthesis using a two-dimensional descriptor

Communications Chemistry, Год журнала: 2025, Номер 8(1)

Опубликована: Фев. 3, 2025

Electrochemical synthesis routes powered by renewable electricity can provide sustainable chemical commodities replacing conventional fossil-based processes. Increasing research focuses on value-added chemicals like the indispensable fertilizer urea, which also constitutes a study case for electrochemical CN-coupling. To guide identification of highly selective catalysts, we aim to new insight analysing existing experimental data selectivity transition metal catalysts towards electrochemically synthesized urea. Firstly, project high dimensional using principal component analysis (PCA) lower dimensions, and thereby confirm that urea is correlated with CO NH3. Furthermore, identified most suitable two-dimensional descriptors prediction out various adsorption energies calculated density functional theory (DFT). We suggest *H *O slabs predict in co-reduction CO2 nitrite ( NO2- ).

Enhanced Electrocatalytic Urea Synthesis over Iron-Doped InOOH Nanosheets under Ambient Conditions

Inorganic Chemistry, Год журнала: 2024, Номер 63(44), С. 20935 - 20939

Опубликована: Окт. 25, 2024

Ambient urea synthesis via C–N coupling from CO2 and nitrate reduction offers an attractive alternative to the Bosch-Meiser route, but it is hindered by lack of efficient catalysts. Herein, we report that Fe-doped InOOH nanosheets effectively catalyze coreduction nitrate, giving a high Faradaic Efficiency 26.9%, yield rate 980.6 μg h–1 mgcat.–1, good durability. Theoretical calculations further elucidate iron dopants can tailor reactivity In site, facilitating hydrogenation key *CO2NH2 intermediate suppressing hydrogen production with higher energy barrier.

Electrocatalytic and Photocatalytic N2 Fixation Using Carbon Catalysts

Nanomaterials, Год журнала: 2025, Номер 15(1), С. 65 - 65

Опубликована: Янв. 2, 2025

Carbon catalysts have shown promise as an alternative to the currently available energy-intensive approaches for nitrogen fixation (NF) urea, NH3, or related nitrogenous compounds. The primary challenges NF are natural inertia of molecules and competitive hydrogen evolution reaction (HER). Recently, carbon-based materials made significant progress due their tunable electronic structure ease defect formation. These properties significantly enhance electrocatalytic photocatalytic reduction (NRR) activity. While transition metal-based solved kinetic constraints activate bonds via donation-back-π approach, there is a problem: d-orbital electrons these metal atoms tend generate H-metal bonds, inadvertently amplifying unwanted HER. Because this, timely review defective electrocatalysts imperative. Such will succinctly capture recent developments in both experimental theoretical fields. It delve into multiple engineering advance development ideal photocatalysts. Furthermore, this carefully explore correlation between photocatalysts Finally, novel introduced obtain more efficient performance NF, paving way sustainable future.
