hydrocarbons. Obviously, the influence of the porous structure of the support was quite complicated [ 7 ]. Recently, mesoporous molecular sieves due to their high surface areas and narrow pore size distribution were used as the support for preparing Co-based FT

Specific surface area, pore volume and pore size distribution of the catalyst were obtained from the N 2 adsorption–desorption measurements on a Quantachrome NOVA-2200e automated gas sorption system. The samples were pretreated in vacuum at 200 °C for 12 h

in oxidation reactions [ 4 , 9 , 20 ]. Recently, many nanostructured mesoporous oxides with high surface area and uniform pore size distribution have been used as supports for multiple catalyst applications. For example, nanostructured mesoporous

. The surface area and pore volume of catalysts were measured by the BET method, and the pore size distributions were detected using the BJH method, both of which was performed by a surface area analyzer (TriStar II 3020, Micromeritics, USA). XPS was

Au loaded on SiO 2 were analyzed by atomic absorption spectroscopy (AAS, Varian 240FS). N 2 adsorption/desorption isotherms were obtained at −196 °C on an Omnisorp 100CX instrument, and pore size distributions were determined from desorption branch
