“…Both supported systems obtained, the organobimetallic (Pt(M 0 Bu 4-x ) y /SiO 2 ) and the bimetallic (PtM 0 y /SiO 2 ), have shown interesting catalytic properties in terms of activity, selectivity and stability [30][31][32][33].…”

Platinum-germanium and platinum-tin catalysts supported on silica, containing different amounts of Sn and Ge, were synthesized using the surface organometallic chemistry on metals technique. The catalysts were characterized using transmission electron microscopy, X-ray photoelectron spectra and X-ray absorption near edge structure and extended X-ray absorption fine structure; and were tested in the liquid-phase selective hydrogenation of furfural. The atomic ratio between the two metals resulted the key factor towards the optimization of the activity and selectivity of the bimetallic catalysts. The bimetallic catalysts were more active than the parent Pt/SiO 2 catalyst in the hydrogenation of furfural. These results can be accounted for by considering a new type of active site having an architecture which would favor the hydrogenation of the C=O group is created, allowing an increased activity towards obtaining furfuryl alcohol. All the studied systems allowed to obtain furfuryl alcohol with high selectivity.

“…The hydrogenation products verbanone (2a) and verbanol (2b) are building blocks in the synthetic and fine chemistry, e.g. in the preparation of taxol (important compound in cancer treatment) [43,44]. In a consecutive reaction step, the dehydration-hydrogenation of 2b to pinane (cis-2c and trans-2c) is possible.…”

The use of modern microwave equipment affords an easy and safe handling in the laboratory routine. The described quartz reactor system was tested in different reaction types to show its versatile applications. Various liquid-phase hydrogenations were carried out successfully. The construction of the reactor allows the direct introduction of gases into the reaction mixture so that the reduction can be performed with gaseous hydrogen.

“…Metal nanoparticles exhibit excellent catalytic activity for the hydrogenation reaction owing to their quantum size and surface effect . To prevent the aggregation of metal nanoparticles, a stabilizer or supported catalyst is usually applied in the catalytic system . Touaibia's team has systematically studied solvent‐free hydrogenation of pinenes over heterogeneous catalysts based on different active metals (Pd, Pt, Ru, and Rh) and supports (carbon, silica and alumina), and the results show Ru/C provides the best catalytic activity under 2.75 MPa H 2 .…”

A multifunctional nanomaterial (Fe3O4@SiO2@CX@NH2) comprising a magnetic core, a silicon protective interlayer, and an amphiphilic silica shell is successfully prepared. Ru nanoparticles catalyst loaded on Fe3O4@SiO2@CX@NH2 is used in hydrogenation of α‐pinene for the first time. The novel nanomaterial with amphipathy can be used as a solid foaming agent to increase gas–liquid–solid three‐phase contact and accelerate the reaction. Under the mild conditions (40 °C, 1 MPa H2, 3 h), 99.9% α‐pinene conversion and 98.9% cis‐pinane selectivity are obtained, which is by far the best results reported. Furthermore, the magnetic nanocomposite catalyst can be easily separated by an external magnet and reused nine times with high selectivity maintaining.
