Well-dispersed Pd particles supported on ordered mesoporous SBA-15 were synthesized by the incipient wetness impregnation of SBA-15 with PdCl2 as precursor. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen adsorption–desorption isotherms, inductively couple plasma atomic emission spectrometry (ICP-AES), and there was revealed an excellent dispersion of Pd nanoparticles in the mesoporous SBA-15 channels. Furthermore, Pd/SBA-15 mesoporous material was used as catalyst for hydrogenation of rosin and exhibited a highly catalytic activity and reusability at least after five recycles.
