Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach

open access: yesAdvanced Materials, EarlyView.
Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...

Unique Impacts of Scandium Doping on Electrode Performance of P’2‐ and P2‐type Na2/3MnO2

open access: yesAdvanced Materials, EarlyView.
The structural stability during electrochemical cycling for P’2‐Na2/3MnO2 as a positive electrode for of Na‐ion battery is investigated by modulating the materials via metal substitution and varying the degree of Jahn‐Teller distortion. The cycle stability is maximized when combining Sc doping and the lattice distortion, demonstrating > 300 cycles in ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Acidity‐Mediated Metal Oxide Heterointerfaces: Roles of Substrates and Surface Modification

open access: yesAdvanced Materials, EarlyView.
The role of local space charge, not only at heterointerfaces, but also at grain boundaries, influenced by surface acidity modulation is elucidated through model platforms composed of Pr‐doped ceria (mixed ionic‐electronic conducting oxide) nanowire arrays.
