On‐Surface Friedel–Crafts Alkylation Through a Stabilized Intermediate Complex

Angewandte Chemie International Edition, EarlyView.
On‐surface Friedel–Crafts alkylation is demonstrated on Ag(111) at the single‐molecule level. STM, XPS, and DFT calculations uncover the reaction mechanism and explain the stabilization of the key intermediate, providing insight into noble‐metal‐surface‐mediated Csp3${\rm C}_{sp^{3}}$─Csp2${\rm C}_{sp^{2}}$ coupling. ABSTRACT The incorporation of sp3${\

Unraveling the Importance of Surface Hydrogen Diffusion in Photocatalysis by Isotope Probing

Angewandte Chemie International Edition, EarlyView.
Surface hydrogen diffusion on titanium dioxide is identified as a crucial step in photocatalytic hydrogen evolution. Demonstrated by deuterium substitution in methanol, restricted diffusion to the co‐catalyst leads to hindered formation of molecular hydrogen and a high KIE.

Overview of Research Progress and Development of Cathode Materials for Aqueous Na‐Ion Batteries

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aqueous sodium‐ion batteries (ASIBs) have now been viewed as the promising energy storage technique for the grid application due to their intrinsic safety and cost‐effectiveness. However, their energy density and cycling stability are still unsatisfactory accompanied by the narrow electrochemical stability window of water and parasitic side ...

Electronic‐Structure Control of Ferromagnetism in Fe3GeTe2 and Fe3GaTe2: A Short Review

Advanced Physics Research, EarlyView.
Fe3GeTe2 and Fe3GaTe2 form a revealing materials pair for examining how carrier filling, orbital hybridization, magnetic anisotropy, and defects cooperate in metallic van der Waals ferromagnets. This Short Review interprets Ga substitution as chemical electronic‐structure engineering rather than simple rigid‐band doping and identifies decisive ...
