The polyaniline composition by silica based mesoporous hollow nanosphere (silica-HNS) was synthesized and selected as a promising solid support for palladium nanoparticle stabilization. Then the nanocomposite was applied as a nanocatalyst for aerobic benzyl alcohol oxidation reactions. Catalyst recyclability showed six successful runs for the reaction. TEM and SEM-EDX/mapping images were used to study the structure and morphology of the Pd-NPs@PANI/HNS. FT-IR spectroscopy, Thermal gravimetric analysis (TGA), and BET were used to characterize and investigate the catalyst nature. In addition, the amounts of Pd loading were characterized by ICP-AES technique. (C) 2018 The Society of Powder Technology Japan. Published by Elsevier B.V. and The Society of Powder Technology Japan.
