摘要：In this paper, a novel organosiloxane was prepared and employed as mesoporogen to synthesis mesoporous zeolite Beta successfully. With the increase of organosiloxane to synthesis mixture, the total BET (Brunauer-Emmett-Teller) surface areas of the as-obtained samples increased initially and then decreased. When the mesoporogen/SiO2 ratio was 0.0142, the prepared zeolite sample had the largest BET surface area up to 810 m(2)/g. The DFT pore size distribution shows that the resulting mesoporous zeolite Beta samples have mesopore size distributions of approximately 2-6 nm. SEM images exhibit the morphology of the samples comprised ellipsoidal particles of 400-500 nm, and its surface is similar to a cracked cauliflower. From the TEM images, large numbers of worm-like mesopores and the basic crystal structure of the mesoporous zeolite Beta are clearly presented.
