Atomically Dispersed Cobalt on Ionic Carbon Nitrides for Selective and Efficient Nitrate Electroreduction to Ammonia

Angewandte Chemie, EarlyView.
By exploiting the structural benefits of PHI, we synthesized CoPHI with atomically dispersed cobalt sites at high density. This architecture enables efficient nitrate ion adsorption, promotes water dissociation, and enhances *H generation on the catalyst surface, thereby significantly improving electrochemical nitrate reduction performance.

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

Angewandte Chemie, EarlyView.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...

Stable Isotopes

2016
Abstract Stable isotopes provide traceability throughout the ocean. The isotopes of a given chemical element have the same electronic structure and the same chemical behavior but slightly different weights. Therefore, slight variations of their relative abundance occur in nature because the atom diffusion speed and the atom bond strength
