A　series　of　adsorptive　materials　which　contain　Ni,　Co,　W　and　Si　were　prepared　by　several　methods.　X-ray　powder　diffraction　(XRD),　Fourier　transform　infrared　spectroscopy　(FT-IR),　Raman,　ultraviolet　visible　spectroscopy　(UV-vis)　and　N-2-physisorption　were　used　to　investigate　surface　characterization　and　pore　structures.　The　results　showed　that　samples　prepared　by　two-step　method　were　complete　amorphous　cosolute　structures　with　the　special　covering　layers.　The　analysis　of　NH3-temperature　programmed　desorption　(NH3-TPD)　illustrated　that　the　different　introduction　methods　of　Co　and　W　would　made　the　distribution　of　acid　sites　of　samples　adjustable.　When　these　adsorptive　materials　were　mixed　with　real　diesel　(Chinese　IV　standard,　initial　concentration　of　sulfur-containing　compounds　C-0　=　32.78　mgS　l(-1),　adsorbents/oil　ratio　of　1　g/30　ml)　at　60　degrees　C　for　2　h,　the　best　desulfurization　rate　could　reach　41.20%.　This　study　of　cosolute　amorphous　material　could　provide　a　reference　for　further　studies.
