Palladium nanoparticles captured onto spherical silica particles using a urea cross-linked imidazolium molecular band.
Palladium nanoparticles were captured onto spherical silica particles using a molecular band composed of imidazolium chloride and urea moieties to form raspberry-like Pd@SiO2 composites, which can be recovered and reused without any loss of catalytic activity in Suzuki-Miyaura coupling.
