A series of carbon material-supported Pd catalysts was prepared and used for hydrogenation debenzylation of hexabenzylhexaazaisowurtzitane (HBIW). The structures and morphologies of carbon supports were characterized by field emission scanning electron microscopy (FESEM), physical adsorption, and Raman spectroscopy. X-ray diffraction (XRD), H-2-TPR, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) were used to characterize Pd-supported carbon. The species Pd, with the states, Pd degrees and PdOx, were presented to the catalysts and can be reduced to Pd degrees as the active centers during the reaction. Among layer, tube, and ordered/disordered pore structures, disordered mesoporous carbon exhibited a high content of Pd on the surface and can be used as an efficient support in terms of high catalytic activity and good recycled stability for hydrogenation debenzylation of HBIW.
