Electrode–Electrolyte Engineering and In Situ Spectroscopy for Urea Electrosynthesis from Carbon Dioxide and Nitrate Co-Reduction

JACS Au, Journal Year: 2025, Volume and Issue: unknown

Published: April 3, 2025

The biogeochemical cycles of carbon and nitrogen are globally disturbed due to the intensive use fossil fuels fertilizers, which is reflected by accumulation dioxide in atmosphere nitrate water streams. co-electroreduction a promising low-carbon alternative for urea synthesis that would help reestablish both cycles. This Perspective highlights importance rational catalyst electrolyte engineering enable electrochemical synthesis. Although field has gained significant attention over past few years, fundamental research under well-defined conditions remains underexplored. We highlight investigating structure-sensitivity effects on C-N coupling through complementary situ spectroscopy online techniques. Model studies, including surface-sensitive investigations, will be crucial understand molecular mechanisms thus rationally design more efficient systems electrosynthesis, paving way their scalable industrial applications.

Mechanical and Covalent Tailoring of Copper Catenanes for Selective Aqueous Nitrate-to-Ammonia Electrocatalysis

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: April 22, 2025

Electrocatalytic nitrate reduction reaction (NO3RR) for the selective generation of ammonia (NH3) enables removal deleterious pollutants while simultaneously upcycling them into a value-added fertilizer. The development nonprecious metal-derived catalysts such as those featuring copper (Cu) earth-abundant alternatives state-of-the-art precious metal is urgent need yet suffering from activity-selectivity-durability trilemma. Rational design molecular Cu complexes with well-defined coordination structures permitting systematic structure-activity relationship (SAR) investigations key to addressing challenge. Here, series Cu(I) [2]catenane ligands are developed NO3RR electrocatalysts first time. By engineering multiple cationic ammoniums on catenane backbone, acceptance anionic substrate well release ammonium product promoted, thereby facilitating higher Faradaic efficiency and selectivity toward via an 8e- pathway. Of note, mutual Coulombic repulsion between multiply charged overcome by mechanical interlocking that catalyst integrity can be maintained under practical conditions. This report highlights promise employing mechanically interlocked platform customizing redox processes involving proton-coupled electron transfer steps.

One-Step Strategy to Maximize Single-Atom Catalyst Utilization in Nitrate Reduction via Bidirectional Optimization of Mass Transfer and Electron Supply

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

Single-atom catalysts offer exceptional performance but face practical challenges due to complex synthesis and low efficiency caused by mass transfer resistance. In this study, based on a simple one-step pyrolysis method, we designed Cu single-atom catalyst with high active site exposure locally electron-deficient environment (HE Cu1-N4) achieve maximum utilization in electrocatalytic nitrate reduction (NO3RR). Using advanced characterization techniques, confirmed that its unique 3D structure enhances atom reduces (NO3-) Synchrotron radiation DFT calculations showed adjusting the coordination induces local effect atoms, increasing electrostatic attraction NO3-. HE Cu1-N4 achieved 100% NH3 selectivity across wide range of NO3- concentrations, an yield (5.09 mg h-1 mgcat-1) nearly 7-fold higher than conventional unmodified (Cu1-N2, 0.73 mgcat-1). Under pilot-scale conditions, demonstrated strong resistance interference excellent stability water systems. A modification method enhanced single atoms catalysts, significantly improving catalytic activity material. Moreover, straightforward strategy holds promise for large-scale production paving way engineering applications.
