摘要：

Hydrothermally stable and highly ordered cubic mesoporous aluminosilicate has been successfully prepared by using a one-step synthesis route. It consists of introducing the zeolite primary building units into the walls of the material. The synthesized material was analyzed by XRD, N-2 adsorption-desorption, FT-IR, HRTEM and other techniques. The characterization results showed that the hydrothermal stability of the material was greatly improved, while the pore system remained highly ordered. The hydrothermal stability is believed to be related with a novel "core-shell" particle structure that formed during the assembling of alummosilicate precursors with the surfactant molecules together with most zeolite primary building units into the shell.
