Investigation on Mn₃O₄ Coated Ru Nanoparticles for Partial Hydrogenation of Benzene towards Cyclohexene Production Using ZnSO₄, MnSO₄ and FeSO₄ as Reaction Additives

Nanomaterials, 2020
Mn3O4 coated Ru nanoparticles (Ru@Mn3O4) were synthesized via a precipitation-reduction-gel method. The prepared catalysts were evaluated for partial hydrogenation of benzene towards cyclohexene generation by applying ZnSO4, MnSO4 and FeSO4 as reaction ...

(E)-2-Methyl-3-phenylselanyl-4-(phenylsulfinyl)oct-3-en-2-ol

Acta Crystallographica Section E, 2014
In the title compound, C21H26O2SSe, the S atom adopts a pyramidal geometry (bond-angle sum = 304°) and the n-butyl chain shows an extended conformation. An intramolecular C—H...O hydrogen bond closes an S(8) ring.

Regulating the coordination structure of single-atom Fe-NxCy catalytic sites for benzene oxidation

Nature Communications, 2019
Atomically dispersed metal-N-C structures are efficient active sites for catalyzing benzene oxidation reaction (BOR). However, the roles of N and C atoms are still unclear.

Synergistic Effect of Surface Acidity and PtO_x Catalyst on the Sensitivity of Nanosized Metal–Oxide Semiconductors to Benzene

Sensors, 2022
Benzene is a potentially carcinogenic volatile organic compound (VOC) and its vapor must be strictly monitored in air. Metal–oxide semiconductors (MOS) functionalized by catalytic noble metals are promising materials for sensing VOC, but basic ...
