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

Angewandte 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 ...

Remote Electrostatic Effect between Octahedral Ru/Ir‐Complexes and Aromatic Micelles to Improve Their Photofunctions in Water

Angewandte Chemie, EarlyView.
The aqueous‐state encapsulation of cationic Ru(II)/Ir(III)‐complexes is efficiently demonstrated by anionic aromatic micelles via remote electrostatic interactions. The resulting host–guest composites exhibit enhanced metal‐complex‐based emission (∼3 to 10‐fold) and NIR emission through guest‐to‐guest FRET upon co‐encapsulation.

One‐Pot Biphasic Photocatalytic CO2‐to‐Carbonylation Cascades

Angewandte Chemie, EarlyView.
Bioinspired biphasic compartmentalization enables one‐pot cascades where photocatalytic CO2 reduction generates CO for carbonylative cross‐couplings to synthesize complex organic products, including a pharmaceutical. ABSTRACT Photosynthesis compartmentalizes reactions across the thylakoid membrane in vivo to upcycle CO2 into complex chemicals that are ...

Iron‐Photocatalyzed Alkene Chloroaminoxylation: A Platform for Orthogonally Activatable Building Blocks

Angewandte Chemie, EarlyView.
An iron‐photocatalyzed unsymmetrical 1,2‐hetero(atom)difunctionalization of alkenes enables to install orthogonal C–Cl and C–O (alkoxyamine) handles which provides access to diverse nucleophiles via complementary reactivity (SN and photoredox) at two distinct sites. Detailed mechanistic studies elucidate interesting features of the iron catalytic cycle.

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

Angewandte 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.
