By peeling off the carbon film from substrate, carbon nano sheet powders (CNSP) were prepared. The carbon film was fabricated by high energy plasma enhanced chemical vapor deposition method. AFM showed that, its grain size is less than 100 nm, surface roughness Ra is 17.95 nm in a range of 5× 5μm of this film. Raman spectra discovered that there is strong and broadened dispersion peak only about 1580 cm-1 in this film. The shapes of CNSP are various irregular sheets, the smallest sheet is less than 10μm, the largest sheet is larger than 500μm in length, and the sheet is frizzy in width when it is long enough. The BET surface area is 6.66 m2/g and there are no any pore tested by N2 adsorption-desorption isotherms. Isotherm adsorption testing showed that even, when the relative pressure P/P0 larger than 0.3, the adsorption volume is decreased instead. After active elements of Mo and W were carried, the CNSP based catal ysts showed super desulfurizing performance of 459.9 ppm/g or 69.01 ppm/m2 from diesel oil hydrogenation.
