Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, EarlyView.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, EarlyView.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Atomic‐Scale Understanding of Selectivity Control in Nitrate Reduction on Cu(100) Under Acidic and Alkaline Conditions

Angewandte Chemie, EarlyView.
A combination of ab initio molecular dynamics simulations and density functional theory calculations clarifies the pH‐dependent origin of the selectivity of nitrate reduction on Cu(100). ABSTRACT We investigate the nitrate reduction reaction (NO3 RR) on the Cu(100) surface using grand‐canonical density functional theory (GC‐DFT) under constant ...

Dual‐Sabatier Optima: How Reaction Mechanism Determines Activity Volcano Map of Dual‐Atom Catalysts for Oxygen Reduction Reaction

Angewandte Chemie, EarlyView.
Dual‐atom catalysts (DACs) for oxygen reduction reaction (ORR), where the dissociative mechanism dominates, show a dual‐Sabatier optima volcano map, diverging from the classical single‐peak volcano of the associative mechanism. Potential‐dependent microkinetic modeling and interpretable machine learning rationalize experimental data and provide design ...

Multi‐Objective Catalyst Discovery in High‐Entropy Alloy Composition Space: The Role of Noble Metals on the Pareto Front for Oxygen Reduction Reaction

Angewandte Chemie, EarlyView.
Pareto optimal compositions of alloy catalyst for oxygen reduction reaction are uncovered through multi‐objective Bayesian optimization of activity, stability, and material cost in an eight‐element high‐entropy alloy composition space. The substantial Pareto front obtained is compared to experimental literature and analyzed to elucidate the roles and ...

Spin‐State Modulation of Atomic Iron Sites Enables Efficient CO2 Electroreduction in Acid Medium

Angewandte Chemie, EarlyView.
An axial oxygen ligand was added to shift the spin state of the single‐atom Fe site from low to medium spin. This change reduces the interfacial interaction with H3O+ and decreases the *CO desorption energy, thus enhancing CO2RR in acidic media.

Convergent Valorization via Scalable C═N Bond Electrosynthesis Through Metal‐Dopant Interfacial Engineering in a Flow Electrolyzer

Angewandte Chemie, EarlyView.
This study establishes an innovative approach to synthesize organonitrogens featuring C═N bonds efficiently using non‐precious metal‐doped MoS2 in a flow electrolyzer. Fe dopant significantly enhances Faradaic efficiency and yield rate, achieving over 81% and 2630 mmol h−1 g−1 for formaldoxime production. This platform upcycles pollutants into valuable
