Titanium-Mediated Organic Electrosynthesis

ACS Catalysis
Titanium is an earth abundant metal with low toxicity that is able to form complexes that mediate a wide range of organic transformations in both polar and radical manifolds. In context of the latter, the use of Ti-catalysts in electrosynthesis is surprisingly underexplored, considering the great potential for electrochemical (re)-generation of low ...

In Situ Alkali Metal Exfoliation‐Coupled Dilute CO2 Electrolysis to Synthesize Interlayer‐Expanded Graphite for High‐Rate Lithium Storage

Advanced Science, EarlyView.
Converting CO2 into advanced carbon materials capable of meeting the rapid lithium storage demands of lithium‐ion batteries creates a mutually beneficial scenario for both energy and environmental sectors. Here, we propose a stepwise CO2 electrolysis approach to transform dilute CO2 into interlayer‐expanded graphite using molten salt electrolyzers ...

Electrocatalytic C─C Bond Formation Via Cyanide Interception of CO2 Reduction Intermediates

Advanced Science, EarlyView.
ABSTRACT Electrochemical CO2 reduction offers a sustainable route to convert greenhouse gas into high‐value‐added chemicals, yet product distributions remain largely limited to simple C1‐C3 molecules. Here, we report a new reaction in which CO2 reduction intermediates undergo direct C‐C coupling with an external carbon nucleophile under electrochemical

Electron Bridge Enhanced Charge Polarization Enables Efficient and Ultra‐Long Stable Urea Electrosynthesis

Angewandte Chemie, EarlyView.
An electron bridge strategy is developed to regulate charge polarization in Pd1 and Ni1 dual single‐atom sites, promoting CO2 reduction, nitrate reduction, and C–N coupling simultaneously. The resulting catalyst achieves efficient urea electrosynthesis with high activity and record durability over 1700 h.

The Promise and Challenges of Ammonia Electrosynthesis From Dinitrogen and Water Using an Electrochemical Palladium Membrane

Angewandte Chemie, EarlyView.
Electrosynthesis of ammonia from nitrogen gas and water at ambient temperature is demonstrated using a device equipped with an electrochemical palladium membrane, which provides exclusive selectivity for the transfer of protons between the aqueous water oxidation and non‐aqueous nitrogen reduction compartments.

Interfacial Tandem Catalysis Over a CuSn(OH)6/Co Heterostructure Enables Efficient Electroreduction of Nitrate to Ammonia

Advanced Science, EarlyView.
Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.

Direct Solar Power‐Driven Durable Ammonia Electrosynthesis From Nitrate Under Fluctuating Voltage Conditions

Angewandte Chemie, EarlyView.
Isolated Sn sites on Cu(111) induce a highly asymmetric charge distribution, which promotes water dissociation, accelerates key intermediate hydrogenation, and suppresses competing hydrogen evolution. As a result, SnCu111 delivers NH3 Faradaic efficiencies above 90% over an 800 mV potential window and enables stable direct solar power‐driven NH3 ...
