Sharma, Deepika published the artcilePd-Au Supported Reduced Graphene Oxide Catalyst for Carbon- Hydrogen Bond Activation in Benzene, Safety of 4,4′-Dimethyldiphenyl, the publication is ChemistrySelect (2021), 6(28), 7111-7117, database is CAplus.
An improved reduced graphene oxide supported bimetallic palladium and gold catalyst was synthesized for the carbon-hydrogen bond activation of un-activated aromatic organic substrate benzene. XPS anal. has revealed that catalyst contained Au(0) nanoparticles with Pd(II) ions on its surface. The surface of rGO was found to be rich in sp2 carbon content with >C=O groups that most probably provided supporting sites for the gold and palladium metals. The XRD anal. further confirmed that Au(0) nanoparticles with palladium oxide and palladium nanoparticles were present on rGO surface. The catalytic activity of the material was tested towards activation of benzene to form biphenyl as an end product. D. function theory has revealed that Pd(II) ion was the active component that insert itself in between C-H bond of benzene and showed efficiency to interact with oxygen mols. Simultaneously, Au(0) atoms have the tendency to adsorb on the ¦Ð-bonded surface of the catalyst and extend its conjugation that reduced the HOMO-LUMO gap of the catalyst and provided the good catalytic activity.
ChemistrySelect published new progress about 613-33-2. 613-33-2 belongs to catalysis-chemistry, auxiliary class Benzene, name is 4,4′-Dimethyldiphenyl, and the molecular formula is C6H12Br2, Safety of 4,4′-Dimethyldiphenyl.
