Niδ+ Atoms Anchored In Situ on Ultrathin Ni‐Phyllosilicate Nanosheet Ensure High‐Efficient CO2 Reduction into CO at Moderate‐Low Temperature

Advanced Science, EarlyView.
A novel supported Ni‐based catalyst, consisting of abundant Niδ+ atoms with low electron density anchored in situ on ultrathin Ni‐phyllosilicate nanosheet (a‐Niδ+−PSNS, 0< δ ≤1), achieve simultaneous outstanding CO2 conversion and CO selectivity. Their ultrathin nanosheet enables abundant anchored Niδ+ atoms to fully expose and disperse, which can ...

A Sustainable Adhesive Paradigm: Reversibly Reinforcing, Heat‐Free Bonding with Universal Substrates

Advanced Science, EarlyView.
A heat‐free adhesive system, delivering superior adhesion strength across metal, plastic, and glass substrates, is developed. Repeatable bonding with reinforcement instead of strength reduction enables error‐tolerant applications. This design paradigm establishes an eco‐friendly alternative to conventional adhesives, particularly suitable for ...
