Coordinating Mesopore Geometry and Interfacial Water Dynamics for Iron‐Site Evolution in Nitrate Electroreduction

Angewandte Chemie, EarlyView.
Mesopore geometry programs the working‐state interface of Fe single sites during nitrate electroreduction. Hexagonal channels reorganize interfacial water and accompany the reversible evolution of isolated Fe─O4‐like sites toward Fe─O─Fe‐like motifs, promoting successive hydrogenation toward NH3 with a Faradaic efficiency of 99.1%.

Site‐Specific Molecular Engineering Redirects Radical Pathways for Selective Photocatalytic Coupling of Methane to C2+ Hydrocarbons

Angewandte Chemie, EarlyView.
Site‐specific self‐assembly of alkyl thiols on Au/TiO2 enables precise modulation of interfacial electron distribution and the local microenvironment through covalent Au‐thiolate interactions. This site‐specific molecular engineering synergistically promotes surface kinetics and charge separation, suppressing ·O2−‐driven overoxidation and thereby ...

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex

Angewandte Chemie, EarlyView.
We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

Deprotonation and Alkylation of Weakly Acidic C(sp3)─H Bonds Through In Situ Generation of a Strong Hydride Base From 1,1,3,3‐Tetramethyldisiloxane and Potassium tert‐Butoxide

Angewandte Chemie, EarlyView.
The use of 1,1,3,3‐tetramethyldisiloxane (TMDSO) and potassium tert‐butoxide enables direct alkylation of weakly acidic carbon–hydrogen bonds with alkyl halides. Experimental and computational studies support the formation of a substrate‐associated hydride‐like base, providing a single‐step alternative to the classical deprotonation and electrophile ...

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

Angewandte Chemie, EarlyView.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale
