Dynamic‐FLPs Enabled by Orbital Hybridization Tuning: Boosting 100% CO Selectivity for Dilute CO2‐to‐CO Conversion

Carbon Energy, EarlyView.
This study, for the first time, constructs photostructured dynamic frustrated Lewis pairs (DFLPs) via a p‐p orbital hybridization regulation strategy, achieving the 100% reduction of low‐concentration CO₂ to CO and breaking the stability‐activity trade‐off.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...
