Angewandte Chemie, EarlyView.Precise modulation of Fe–N4 site distances constructs spin‐regulated Fe–N4 twins, triggering a volcano‐type Fenton‐like activity and promoting oriented singlet oxygen generation. The twin‐site catalyst enables highly selective and efficient hospital wastewater purification with simultaneous pharmaceutical degradation and disinfection under low ...

Metal-Organic Framework/Organocatalyst Combinations as Powerful Multicatalytic Systems for Aerobic Oxidations. [PDF]
Angew Chem Int Ed EnglA multicatalytic strategy based on the simple combination of metal‐organic frameworks (MOFs) and organocatalysts is able to mediate challenging aerobic oxidation reactions. The use of earth‐abundant MOFs and commercially available (hydro)quinone co‐catalysts greatly simplify the generation of powerful multicatalytic systems, opening the door for the ...

Analytical Sciences, 2004 The oscillation of the interfacial tension and electrical potential at a water/nitrobenzene interface was observed with homologous anionic surfactant molecules, sodium-alkyl-sulfates. Concerning small molecules with a short hydrophobic carbon chain, the oscillation period and amplitude decreased with a decrease of the length of the alkyl chain.

Angewandte Chemie, EarlyView.This work establishes an MXene‐based S‐scheme heterojunction in which the cooperative interplay among metallic Ni, surface NiOx domains, and conductive Ti3C2Clx drives efficient charge separation and photothermal coupling. Progressive evolution of Ni surface states regulates the CH4/CH3OH product distribution by modulating interfacial energetics and ...
