Oxygen Defect Engineering of Hexagonal Perovskite Oxides to Boost Catalytic Performance for Aerobic Oxidation of Sulfides to Sulfones

Advanced Functional Materials, EarlyView.
Ru‐substituted hexagonal perovskite SrMnO3, featuring face‐shared oxygen species, is designed as an effective heterogeneous catalyst for the aerobic oxidation of sulfides. The catalyst demonstrates high selectivity to sulfones (>99%) under mild reaction conditions (≥30 °C). Ru substitution promotes oxygen vacancy formation of face‐shared oxygen species

Turning on Selective H2S Gas Sensing Activity in Ternary Nickel Tungstate Strongly Correlated Electron System Through Sub‐Gap Band Manipulation

Advanced Functional Materials, EarlyView.
A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...
