AI Technical Summary
The existing SSZ-121 catalyst does not contain boron, limiting its application potential in organic compound conversion reactions.
The new boron SSZ-121 crystalline germanium silicate molecular sieve was successfully synthesized by using 1,3-bis(1-adamantyl)imidazolium cation as structural guide. The method includes preparing a reaction mixture comprising a FAU backbone zeolite, a germanium source, a boron source, a structural guide and water, and crystallizing it under appropriate conditions, followed by removal of the structural guide by calcination or ozone treatment.
The prepared boron SSZ-121 molecular sieve has unique catalytic properties and adsorption/separation capabilities, is suitable for organic compound conversion reactions, and its chemical composition and XRD pattern are characteristic of its calcined form.
