Indium Clusters With 6s2 Lone‐Pair Effect as Excitonic Electron Reservoirs for Direct 2e− Photocatalytic H2O2 Photosynthesis

open access: yesAngewandte Chemie, EarlyView.
This study demonstrates that indium clusters with 6s2 lone‐pair effect anchored on carbon nitride act as excitonic electron reservoirs to boost charge separation and O2 activation for highly selective direct 2e− oxygen reduction. This work establishes cluster‐mediated electron reservoir engineering as a general strategy for enhancing selective ...

Anion Engineering of Surface Frustrated Lewis Pairs for Light‐Assisted CO2 Hydrogenation to Methanol

open access: yesAngewandte Chemie, EarlyView.
Anion engineering through nitrogen incorporation regulates the local coordination environment and promotes the formation of defect‐associated Ga–O/N frustrated Lewis pairs in non‐stoichiometric zinc gallium oxide. The engineered surface sites facilitate heterolytic H2 splitting, while the modified electronic structure enhances light utilization ...

Polypyridyl Coordination Motifs as Precursors for Ordered Carbonaceous Frameworks Toward High‐Density Ru Single‐Atom Catalysts

open access: yesAngewandte Chemie, EarlyView.
Here, we introduce a molecular design principle that fundamentally expands the bottom‐up synthesis of single‐atom catalysts (SACs). Coordinatively flexible polypyridyl units enable bottom‐up formation of ordered carbonaceous frameworks containing atomically dispersed Ru (∼11 wt%) by simple carbonization.

Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization

open access: yesAngewandte Chemie, EarlyView.
Coupling a structurally switchable Cu(I) complex to an organic light‐harvesting chromophore boosts photoinduced intersystem crossing via the transient formation of a Cu(II) intermediate. Spectroscopic, physical, computational, and photocatalytic studies support this unique new approach to solar energy upconversion.

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

open access: yesAngewandte 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
