Selective Catalytic Transformation of Polystyrene into Ethylbenzene over Fe-Cu-Co/Alumina
Publication date: Available online 28 January 2020Source: Journal of Saudi Chemical SocietyAuthor(s): Nouf M. Aljabri, Zhiping Lai, Kuo-Wei HuangAbstractFeCuCo over aluminum oxide catalyst was prepared to catalytically degrade polystyrene (PS) into ethylbenzene (EB) under mild conditions. This catalyst was characterized by XRD, SEM, STEM-EELS, STEM-EDS, XPS, and physical properties. A significant selectivity toward EB formation at 250 °C was achieved in the absence of hydrogen with 82% liquid yield. End-chain session and cross-linking reactions are proposed to be the dominant pathways in the degradation of PS over FeCuCo ...

Magnetism and Application of NiFe@Au Nanoparticles
This report describes the synthesis of magnetic NiFe@Au (i.e., NiFe core with Au shell) nanoparticles as functional spectroscopic probes. Both of the magnetic NiFe nanoparticles and its composite NiFe@Au particles were synthesized in aqueous solution. It is more analogous with the biological organism environment. The composite nanoparticles were dispersible in aqueous solution and could be directed by a magnetic field. Such NiFe@Au nanoparticles have been shown to function as magnetic and spectroscopic nanoprobes for surface enhanced Raman scattering (SERS) detection of molecules attached to the surface of the nanoparticle...
