Реферат:
The ordered mesoporous Mg- and Ni-Mg-alumina samples of general formula xwt%Mg-Al2O3 and ywt%Ni-x wt%Mg-Al2O3 (x, y = 5, 10 % wt) have been prepared by the one-pot evaporation induced self-assembly (EISA) method using as a template Pluronic P123. The textural and structural properties of the prepared samples have been characterized by N2 adsorption-desorption analysis, BET, XRD, TEM with EDX, HAADF-STEM, H2-TPR. The samples calcined at 700C had the ordered mesoporous structure with the SSA of 170-250 m2/g, pore volume of 0.5-0.64 cm3/g and narrow distribution of the pore size (the mean size 12-16 nm). For the catalysts prepared by the one-pot EISA method, the size of metal Ni particles was in the range of 3-12 nm that was conditioned by their confinement in the mesopores and the interaction with MgO and Al2O3. Testing in methane dry reforming in the feed 15v.% CH4+ 15v.%CO2, He balance at 650-750°C and contact time 0.015 s has shown the higher activity and stability of the ordered mesoporous 10w%Ni-10w%Mg-Al2O3 catalysts prepared by the one-pot method as compared with the catalyst of the same composition obtained by impregnation.
