Chirality‐Driven Piezocatalysis in MOFs: Achieving Efficient Cocatalyst‐Free Hydrogen Evolution

Angewandte Chemie, EarlyView.
We report a chirality‐driven post‐synthetic modification strategy that grafts chiral L‐histidine (L‐His) onto the Hf6 clusters of MOF‐808(Hf), which significantly boosts the piezoelectricity and charge transfer efficiency, thus significantly enhancing the piezocatalytic performance of MOF‐808(Hf).

Atomically Correlated Phosphorus–Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production

Advanced Science, EarlyView.
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...

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 ...

Learning Work Function via Implicit Reasoning on Electrostatic Potential Landscapes

Advanced Science, EarlyView.
StructPot‐CLR establishes a cross‐modal contrastive learning framework that aligns the crystal structures of 2D materials with plane‐averaged electrostatic potential landscapes for physically informed work‐function prediction. The model achieves an MAE of 0.265 eV and an R2 of 0.902 on the held‐out test set while accurately preserving key morphological
