The bimetal catalyst Pt-Cu/SiO2 was prepared by the impregnation method. Its catalytic performance was investigated by the selective hydrogenation of cinnamaldehyde. Pt-Cu/SiO2 exhibited much higher selectivity (64.1%) to cinnamyl al

Catalysts made of Pt nanoparticles dispersed on graphene (X wt%Pt/G, X=2.0, 3.5, and 5.0) were prepared and characterized by XRD, Raman spectroscopy, BET surface area measurements, TEM, and X-ray photoelectron spectroscopy (XPS), and a 3.5 wt% Pt supported on Vulcan Carbon catalyst (3.5 wt%Pt/VC) was included as a reference. Although the mean Pt nanoparticle size is approximately 4.4 nm for all X wt%Pt/G and 3.5 wt%Pt/VC catalysts, cinnamal alcohol was produced with high selectivity only with the graphene-supported catalysts: 92% conversion and 88% selectivity toward cinnamal alcohol were obtained with 3.5 wt%Pt/G. This catalyst also showed good stability in recycling tests. The good selectivity observed with the graphene-based catalysts is attributed to the higher fraction of reduced surface Pt0 atoms seen on the surface of the Pt nanoparticles (determined by XPS). This interpretation is consistent with DFT calculations. Additional π -π interactions between cinnamaldehyde and graphene may also play a role in the selective hydrogenation of cinnamaldehyde.

An efficient and selective method for the conversion of allylic, secondary- and tertiary benzylic alcohols into their corresponding ethers in the presence of iron(III) as FeCl3 and Fe(ClO4)3 under solvolytic condition is d
