NH3‐Guided Low‐Temperature Nanostructural Refinement Boosts Visible‐Light‐Driven H2O2 Synthesis in Ionic Carbon Nitrides

open access: yesAdvanced Materials, EarlyView.
A nanostructural refinement strategy is reported for KPHI photocatalysts using NH4Cl in a molten salt environment to induce coherent domain fragmentation and controlled cyano defect formation. This dual modification promotes n→π* transitions, enhances charge separation, and accelerates ORR kinetics, yielding exceptional AQY values of 49% (410 nm) and 5%

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

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 ...

Mechanochemical Nitrous Oxide Decomposition

open access: yesAdvanced Materials, EarlyView.
Nitrous oxide (N2O) is a potent greenhouse gas with a global warming potential of 310. A novel mechanochemical strategy is presented for decomposing N2O into harmless nitrogen and oxygen, achieving a rapid decomposition rate of 1761.3 mL h−1 and nearly complete N2O conversion of 99.98% at 42 °C.

Oriented Crystallization of Perovskite Film via Fluorine‐Containing Hyperbranched Polymer for Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
A fluorine‐containing hyperbranched polymer is developed to guide oriented crystallization and construct a cross‐linked hydrophobic network, enabling the formation of high‐quality perovskite films with enhanced environmental stability. The resulting devices deliver a PCE of 26.05% (0.04 cm2) and 22.43% (16.1 cm2), while maintaining 97% of their initial
