Copper Single‐Atom Catalyst for Efficient C─S Coupling in Thioether Synthesis

Angewandte Chemie, EarlyView.
We report the first single‐atom catalyst for C─S cross‐coupling, featuring atomically dispersed Cu sites on mesoporous carbon nitride. The catalyst enables efficient, selective, and recyclable thioether synthesis under mild conditions and on a gram scale.

Metal‐Organic Open‐Framework Molecular Magnet Based on Vanadium Hexacyanoferrate Prussian Blue Analogs as Cathode Material for Advanced Potassium Ion Aqueous Battery

Advanced Energy and Sustainability Research, EarlyView.
An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...

From Flue Gas to Syngas: Composite Electrode Based on Ionic Liquid and Microporous Polymer for MEA‐Based CO2 Electrolysis

Angewandte Chemie, EarlyView.
A composite gas‐diffusion electrode (GDE) with a thin CO2‐selective interlayer beneath the catalyst facilitates direct MEA electrolysis of simulated flue gas (with O2) to CO/syngas, eliminating costly pre‐purification. The interlayer—an intrinsically microporous polymer scaffold infused with CO2‐philic [Emim][BF4]—delivers high CO2/N2 and CO2/O2 ...

Defect Engineering in Semiconductor Photocatalysts: Enhancing Photocatalytic Activity for Green Energy Production

Advanced Energy and Sustainability Research, EarlyView.
By creating anion and cation vacancies, scientists fine‐tune semiconductor bandgaps and extend light absorption, boosting charge separation in photocatalysts. Surface defects enhance reactant adsorption and carrier transport, while controlled bulk defects curb recombination.
