Recently, the development of eco-friendly mechanochem. approaches for the preparation of novel ysts with enhanced activity and selectivity has gained considerable attention. Herein, we developed a rapid and solvent-less mechanochem. method for the preparation of mixed metal oxide (Ag2O-MnO2) decorated graphene oxide (GRO)-based nanocomposites (Ag2O-MnO2/(X weight%)GRO), as the Ag2O-MnO2/(X weight%)GRO nanocomposite was fabricated by the phys. grinding of freshly prepared GRO and pre-annealed (300°C) mixed metal oxide nanoparticles (NPs) (Ag2O-MnO2) using an eco-friendly milling procedure. The as-prepared nanoysts were characterized by using various techniques. Furthermore, the nanocomposites were applied as a heterogeneous yst for the oxidation of alc. by employing gaseous O2 as an eco-friendly oxidant under base-free conditions. The mechanochem. obtained GRO-based composite exhibited noticeable enhancement in the surface area and ytic performance compared to the pristine Ag2O-MnO2. The results revealed that (1%)Ag2O-MnO2/(5 weight%)GRO yst exhibited higher specific performance (13.3 mmol.g-1.h-1) with a 100% conversion of benzyl alc. (BnOH) and >99% selectivity towards benzaldehyde (BnH) within 30 min. The enhancement of the activity and selectivity of GRO-based nanoyst was attributed to the presence of various oxygen-containing functional groups, a large number of defects, and a high sp. surface area of GRO. In addition, the as-prepared nanoyst also demonstrated excellent ytic activity towards the conversion of a variety of other alcs. to resp. carbonyls under optimal conditions. Besides, the yst ((1%)Ag2O-MnO2/(5 weight%)GRO) could be efficiently recycled six times with no noticeable loss in its performance and selectivity. In the experiment, the researchers used many compounds, for example, 5-Hexen-1-ol(cas: 821-41-0Related Products of 821-41-0)
5-Hexen-1-ol(cas: 821-41-0) is a volatile organic compound. Further, it is used to prepare 6-bromo-hex-1-ene by reaction with phosphorus tribromide.Related Products of 821-41-0
