Recycling Ni‐Rich NCM Cathode Materials From Spent Li‐Ion Batteries as Efficient Electrocatalyst for Urea Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mounting battery waste demands sustainable solutions. We recycle spent NCM cathodes into high‐performance urea oxidation catalysts, enabling sustainable hydrogen production and simultaneous urea waste treatment. The burgeoning electric vehicle industry has intensified the demand for high‐energy Ni‐Co‐Mn (NCM) cathodes, yet their end‐of‐life management ...

Isoreticular Metal–Covalent Organic Frameworks With Engineered π‐Conjugation for Efficient Photocatalytic Hydrogen Production

Electron, EarlyView.
By constructing an isoreticular Cu3‐cluster‐based metal–covalent organic framework platform with systematically tunable π‐conjugation, the physicochemical properties can be finely modulated within a well‐defined structural framework, thereby establishing a precise conjugation–performance correlation to govern the charge separation/transport, and thus ...

Intramolecular C–H Nitrene Insertion Catalyzed by Single‐Atom Cobalt on Nitrogen‐Doped Carbon

Helvetica Chimica Acta, EarlyView.
A cobalt single‐atom catalyst was applied to intramolecular C(sp3)–H nitrene insertion to synthesize benzosultams. The catalyst was reused for 17 times with cumulative turnover number 340. ABSTRACT Single‐atom catalysts (SACs) are advancing heterogeneous organic synthesis by combining the molecular precision of homogeneous complexes with the ...

Effect of Metal–Metal Distance on the Performance of Dual‐Atom Catalysts for the Oxygen Reduction Reaction: A Density Functional Theory and Micro‐kinetics Study

Small, EarlyView.
Density functional theory calculations and microkinetic modeling were carried out on 108 dual‐atom catalysts with varied metalmetal distances ranging from 2.2 to 3.5 Å. The results reveal that moderate spacing of around 3.0 Å promotes bridging oxygen adsorption and dissociative reduction pathways, weakens the hydroxylhydroperoxyl scaling relationship ...
