Mechanochemical Piezoelectric Catalysis: Advancing the Hydrogenation of Alkenes
Advanced Science, EarlyView.This study presents mechanochemical piezoelectric catalysis for alkene hydrogenation, eliminating the need for transition metals, H2, and solvents. The method effectively hydrogenates diverse activated and unactivated alkenes and shows potential for modifying bioactive molecules in pharmaceuticals.

Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing
Advanced Science, EarlyView.Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...

Adaptive Cu Reconstruction in Heterostructure Drives High‐Rate Nitrate‐to‐Ammonia Conversion
Advanced Science, EarlyView.An adaptively reconstructed Cu/CoOX heterojunction, featuring a surface‐localized, hydroxyl‐rich oxidized Cu species, forms in situ from a CuO/CoOX (Co1Cu9OX) pre‐catalyst during electrochemical nitrate reduction. The self‐adaptive reconstruction and the incorporation of heterostructure regulate nitrogen‐containing intermediate adsorption and *H supply,

A Molten Salt Extraction Method for Palladium Recovery via the CaPd2 Intermetallic Compound
Advanced Science, EarlyView.A designed Ca → CaPd2 → Pd pathway enables acid–free palladium recovery in molten salt. Calcium alloying forms anionic CaPd2, which is selectively oxidized by iodine from CaI2 to yield high–purity metallic Pd. ABSTRACT To address palladium scarcity and the low efficiency of conventional recovery processes, this work presents a molten–salt extraction ...
