Mesoscopically ordered, hydrothermally stable metal oxide-block copolymer composite or mesoporous materials are described herein that are formed by using amphiphilic block polymers which act as structure directing agents for the metal oxide in a self-assembling system.

Block copolymer processing for mesostructured inorganic oxide materials

The low stability of some molecular sieves can be overcome during calcination by a solid state reaction between the molecular sieve and a salt. Molecular sieves including zeolites, metal substituted aluminosilicates, and metallosilicates can be stabilized by this method. The inventive process comprises mixing such molecular sieve with a salt, either directly or as a slurry; and then heating the resulting mixture to remove water, organics and adsorbed species.

Stabilization of molecular sieves by salt addition

Mesoscopically ordered, hydrothermally stable metal oxide-block copolymer composite or mesoporous materials are described herein that are formed by using amphiphilic block copolymers which act as structure directing agents for the metal oxide in a self-assembling system.

A low silica AFI zeolite and a high purity gmelinite zeolite that have a SiO /Al O ratio of about 10 or less are provided.
