Bimetallic Ru:Co nanoparticles stabilized by PEG and imidazolium ionic liquid have been successfully synthesized and characterized. The supported Ru:Co mesoporous nanoparticles catalyst showed excellent catalytic activity in the Suzuki-Miyaura cross-coupling reaction and maintained good stability after multiple cycles.
Bimetallic Ru:Co nanoparticles stabilized by PEG and imidazolium ionic liquid based [KIT-6] mesoporous silica, denoted as Ru:Co NPs@ [KIT-6]-PEG&imid 6, has been synthetized by post grafting method and fully characterized by SEM, TEM, XPS, FT-IR and solid-state C-13 and Si-29 NMR spectroscopy. The supported Ru:Co mesoporous nanoparticles catalyst 6 revealed excellent catalytic activity (conversions up to 100%), turnover number (TON) of 770 and turnover frequency (TOF) of 7700 h(-1) in the Suzuki-Miyaura cross-coupling of p-bromobenzonitrile and phenylboronic acid in H2O:EtOH (1:1) solution under very mild reaction conditions. In addition, the heterogeneous catalyst 6 maintains almost its inherent catalytic activity after the 6th catalytic recycle. [GRAPHICS] .
