Investigation On Pd/SeO2/SiO2 For α-Pinene Oxidation. Characterization by Transmission Electron Microscopy (TEM)

Abstract

To selectively obtain myrtenal, it is proposed to design a heterogeneous catalyst selective, active, stablewith low selenium load, reusable and efficient to produce the expected aldehyde. In this work, aPd/SeO2/SiO2 catalyst was prepared and tested for the allylic oxidation reactions of α-pinene toselectively obtain a good yield to the desired myrtenal product. To do this, we rely on the selectivity ofSeO2 and the oxidative capacity of Pd. The catalyst is made up of Pd nanoparticles supported on SeO2modified silica [7]. The Pd/SeO2/SiO2 catalyst characterization was carried out mainly by TransmissionElectron Microscopy (TEM) and also by XRD, FTIR, and XPS. TEM study was performed fordetermining Pd particle size both over fresh and used catalyst.
