Fast Synthesis

A reconstruction strategy for the fast synthesis of mesoporous SAPO molecular sieve single crystals has been developed. The synthesized mesoporous SAPO-34 single crystals exhibit excellent hydrothermal stability and high catalytic activity in the MTO reaction.

Mesoporous Aluminosilicate

A highly ordered mesoporous aluminosilicate molecular sieve, designated as MSAMS-4, has been synthesized via multistage recrystallization. Hydrothermal-stability tests revealed that MSAMS-4 has retained a well-ordered hexagonal-symmetry mesostructure both after treatment with 100 °C water for 120 h and after steaming at 800 °C for 6 h.Key words: aluminosilicates molecular sieves, mesoporous materials, multistage recrystallization, hydrothermal stability.
