Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

open access: yesCarbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Unveiling Synergistic CuAuAg Nanoparticles on CuO for High‐Yield CO2 Electroreduction

open access: yesCarbon Energy, EarlyView.
Pulsed laser irradiation in liquid synthesis was employed to fabricate a trimetallic catalyst composed of CuAuAg nanoparticles uniformly decorated on CuO nanosheets (CuAuAg/CuO composite). This catalyst exhibits remarkable electrocatalytic performance for the reduction of CO2 to CO, achieving a high CO yield rate of 5.1 mmol h−1 cm−2 and a Faradaic ...

Oxygenophilic Cerium Promotes Active Species Generation and Modulates the Interfacial Water Network in Electrocatalytic Water Oxidation

open access: yesCarbon Energy, EarlyView.
CeO2 dendrites are introduced to modify the NiSx/C3N4 nanorods, constructing hexagonal star‐like forest arrays (CeO2@NiSx/C3N4). The oxophilicity of Ce species generates abundant oxygen vacancies, which subsequently facilitate the in situ evolution of active amorphous NiOOH.

Tribochemical Surface Modification of Silicon

open access: yesChemistry – A European Journal, EarlyView.
Mechanical scribing activates silicon surfaces by generating reactive sites that spontaneously graft alcohol‐, thiol‐, and alkyne‐terminated molecules under ambient conditions. Within 10 s, high‐coverage, electroactive organic layers form without light, heat, or applied voltage, offering a rapid tribochemical route to functional silicon interfaces for ...
