During the last two decades, with the development of nanotechnology, various
nanomaterials have been designed and generated. Among them, hybrid
organic–inorganic nanoparticles as a particular immobilizing carrier of the catalyst active sites have shown an important contribution in the current research
studies. This is due to the large area and loads of active sites. This prominent
review is focused on the novel various exa about the immobilization of
nanoparticles with organic compounds as versatile and efficient catalysts in
organic syntheses.
