Thermally Regulated Methanol Selectivity in Photo‐Thermo Methane Oxidation Through Interfacial Methyl Transfer

Advanced Science, EarlyView.
Photo‐thermo cascade catalysis enables highly selective methane‐to‐methanol conversion over Au‐ZnO, achieving a CH3OH production rate of ∼800 µmol h−1 with 86% selectivity. Thermal activation gates the transfer of methane‐derived methyl intermediates from ZnO to Au, thereby redirecting the reaction pathway toward methanol formation. ABSTRACT The direct

Ag─S Sites Steer Furfural Electroreduction to Furfuryl Alcohol

Angewandte Chemie, EarlyView.
A simple sulfide incorporation strategy turns silver into a highly active and selective catalyst for furfural electroreduction to furfuryl alcohol. Experiments combined with density functional theory reveal how isolated S sites promote hydrogenation while suppressing hydrofuroin coupling, enabling selective biomass upgrading.

Interface‐Confined Cavitation at an MXene/TiO2 Schottky Heterointerface for Non‐Thermal Juice Preservation

Advanced Science, EarlyView.
This work establishes an MXene/TiO2 Schottky heterointerface for non‐thermal sonocatalysis. Interface‐confined cavitation and dynamic Ti3+/V₀ shuttles drive charge transport and reactive oxygen species (ROS) generation. The platform achieves 3‐log pathogen reduction while retaining heat‐labile nutrients in complex food matrices, redefining sonocatalyst

Operando Identification of the Active Phase in Sr‐Promoted Lanthanum Cobaltite Perovskite‐Derived Catalysts for Ammonia Decomposition

Angewandte Chemie, EarlyView.
Ammonia decomposition catalyzed by base metals: Exsolution of cobalt from perovskites prepared by spray‐flame synthesis (SFS) yields highly active, SrO‐promoted Co/La2O3 catalysts with low cobalt content. Operando studies provide insight into the function of the promoter. Dynamic surface reconstruction under operating conditions increases the interface

Electrocatalytic Urea Synthesis From CO2 and N2/NO3−: Bridging Catalyst Activity, C–N Coupling Kinetics, and Industrial Applicability

Advanced Science, EarlyView.
This review compares NO3− + CO2 and N2 + CO2 electrocatalytic urea synthesis in feedstock properties, catalyst design, C–N coupling mechanisms, performance optimization, and engineering applicability. The two systems correspond to a near‐term deployable route and a long‐term green synthesis goal, respectively.

A study of the interface of CeO2/Si heterostructure grown by ion beam deposition

, 1998
Epitaxial cerium dioxide films on single-crystal silicon substrates (CeO2/Si) have been grown by a dual mass-analyzed low-energy ion beam deposition (IBD) system. By double-crystal X-ray diffraction (XRD), Full Width at Half Maximum (FWHM) are 23' and 33'
