Carbon fiber confined mixed Ni‐based crystal phases with interfacial charge redistribution induced by high bond polarity for electrochemical urea‐assisted hydrogen generation

Carbon Energy
Interfacial electronic structure modulation of nickel‐based electrocatalysts is significant in boosting energy‐conversion‐relevant urea oxidation reaction (UOR). Herein, porous carbon nanofibers confined mixed Ni‐based crystal phases of Ni2P and NiF2 are

Low‐Barrier and Canonical Hydrogen Bonds Modulate Activity and Specificity of a Catalytic Triad

Angewandte Chemie, 2019
AbstractThe position, bonding and dynamics of hydrogen atoms in the catalytic centers of proteins are essential for catalysis. The role of short hydrogen bonds in catalysis has remained highly debated and led to establishment of several distinctive geometrical arrangements of hydrogen atoms vis‐à‐vis the heavier donor and acceptor counterparts, that is,

The Influence of the Structure of Organochlorine Compounds on Their Decomposition Process in a Dielectric Barrier Discharge

Reactions
The decomposition efficiency of C2HCl3 and CHCl3 in a barrier discharge is very different, even though these compounds differ little in chemical composition. In both compounds, there are three chlorine atoms and one hydrogen atom.
