Elucidating Photo‐Kinetic Control in Photothermal Reverse Water‐Gas Shift Reaction

open access: yesAngewandte Chemie, EarlyView.
Light directly regulates the rate‐determining step (RDS) in photothermal catalysis. In a Mars–van Krevelen (MvK)‐type reverse water‐gas shift (RWGS) reaction over In‐doped MoO2, light shifts the RDS from the H2‐related reduction half‐reaction to the CO2‐related oxidation half‐reaction, enhancing catalytic activity and lowering the apparent activation ...

Defect‐Rich CoNi Prussian Blue Analogues Enable Highly Selective Electrochemical Hydrogen Peroxide Production

open access: yesAngewandte Chemie, EarlyView.
Introducing [Co(CN)6]3− defects into CoNi Prussian Blue analogues exposes square‐planar Ni–N4 active sites, leading to remarkable H2O2 selectivity during the electrochemical oxygen reduction reaction in alkaline media. ABSTRACT Decentralized electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e− ORR) offers a ...

Engineering Atomically Precise Cu4I4 Nanoclusters With Integrated Adsorption and Hydrogenation Functions for Efficient Photocatalytic Nitrate‐to‐Ammonia Conversion

open access: yesAngewandte Chemie, EarlyView.
Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.

Acetylene Semi‐Hydrogenation by Photocatalysis

open access: yesAngewandte Chemie, EarlyView.
Photocatalytic acetylene semi‐hydrogenation is an emerging light‐driven route to polymer‐grade ethylene, offering a mild alternative to energy‐intensive thermocatalysis. By replacing H2 co‐feed with water or other proton sources, these systems can achieve high selectivity under ambient conditions.

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

open access: yesAngewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...
