The　influence　of　the　surface　chemical　properties　of　the　carbon　support　on　the　Pd　dispersion,　activity　and　stability　of　Pd(OH)(2)/C　catalyst　for　the　hydrogenolytic　debenzylation　of　tetraacetyldibenzylhexaazaisowurtzitane　(TADB)　was　studied　in　detail.　The　flowerlike　nanosheet　carbon　material　(NSC)　was　chosen　as　the　pristine　support,　meanwhile　chemical　oxidation　with　nitric　acid　and　physical　calcination　at　600　degrees　C　treatments　were　used　to　modify　its　surface　properties,　which　were　denoted　as　NSCox-2　(treated　with　20　wt%　HNO3)　and　NSC-600,　respectively.　The　three　carbon　supports　and　the　corresponding　catalysts　of　Pd/NSC,　Pd/NSC-600,　and　Pd/NSCox-2　were　characterized　by　scanning　electron　microscope　(SEM),　transmission　electron　microscopy　(TEM),　nitrogen　sorption　isotherm　measurement　(BET),　powder　X-ray　diffraction　(XRD),　Raman　spectra,　X-ray　photoelectron　spectra　(XPS),　temperature-programmed　desorption　(TPD),　temperature-programmed　reduction　(H-2-TPR),　thermogravimetric　analysis　(TG),　and　element　analysis.　The　debenzylation　activities　of　Pd/NSC,　Pd/NSC-600,　and　Pd/NSCox-2,　as　well　as　the　three　catalysts　after　pre-reduction　treatment　were　also　evaluated.　It　was　found　that　the　activity　and　stability　of　the　Pd(OH)(2)/C　catalysts　in　the　debenzylation　reaction　highly　depended　on　the　content　of　surface　oxygen-containing　groups　of　the　carbon　support.
