In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Crystallographic Distinction between “Contact” and “Separated” Ion Pairs:  Structural Effects on Electronic/ESR Spectra of Alkali-Metal Nitrobenzenides [PDF]

, 2004
The classic nitrobenzene anion-radical (NB-• or nitrobenzenide) is isolated for the first time as pure crystalline alkali-metal salts. The deliberate use of the supporting ligands 18-crown-6 and [2.2.2]cryptand allows the selective formation of contact ...

Asymmetric Active Center Triggers Side‐On Photo‐Fenton‐Like Reaction Through Polar Charge Transfer and Self‐Adapting Sulfur Vacancies

Advanced Science, EarlyView.
The Cu‐Zn3In2S6 photocatalyst (Cu‐ZISV) with asymmetric Cu‐SV‐Zn sites was designed and synthesized to boost peroxymonosulfate (PMS) activation kinetics. The side‐on photo‐Fenton‐like reaction by the asymmetric Cu‐SV‐Zn site accelerated PMS activation and pollutant degradation, and the first‐order kinetic constant of Cu‐ZISV increased by 4.87 times ...

Aromatic nitrations by mixed acid. Slow liquid-liquid reaction regime [PDF]

, 1995
Aromatic nitrations by mixed acid have been selected as a specific case of a heterogeneous liquid-liquid reaction. An extensive experimental programme has been followed using adiabatic and heat-flow calorimetry and pilot reactor experiments, supported by

Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

Advanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.
