Silica Nanoparticle Hyperbranched Polyglycerolsulfuric Acid: The Chemoselective, Efficient, Green and Reusable Nanocatalyst for the Alcohol Oxidation

Nano SiO2/hyperbranched polyglycerol (HPG)/SO3H catalyst was readily prepared for first time from inexpensive starting materials in aqueous media which catalyzed the synthesis of benzoic acid. FTIR spectra, X-ray diffraction (XRD) and transmission electron micrographs (TEM) was employed to characterize the properties of the synthesized nano SiO2/HPG/SO3H. High catalytic activity and ease of recovery from the reaction mixture using filtration and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system
