MESOPOROUS ALUMINOSILICATE MOLECULAR SIEVE: CONTROL OF TEXTURAL PROPERTIES BY POST-SYNTHESIS HYDROTHERMAL REATMENT

By means of sol-gel synthesis with silicon and aluminium alkoxides, Triton X-114, and hydrothermal stabilization at various times and temperatures, were obtained aluminosilicates which have a porous structure (MSA) and are thermally stable and partially ordered. The as-synthesized MSA samples were s...
