Sheet-like particles of zeolite and method for producing same

A method for producing sheet-like particles of zeolite, comprising:

• a first step which comprises
• forming a bilayer in a solvent,
• forming a hyper-swollen lamellar phase of the bilayer by adding, in the solvent, an aluminum atomic source, and at least one atomic source selected from the group consisting of a silicon atomic source and a phosphorus atomic source, and
• forming sheet-like particles of a precursor of zeolite between two monomolecular layers, wherein the two monomolecular layers constitute the bilayer and are formed from amphiphilic molecules;
• and
• a second step of bringing the sheet-like particles of the precursor of zeolite into contact with gaseous water in a container to form the sheet-like particles of zeolite,
• wherein a thickness of the sheet-like particles of the zeolite is 1 nm or more and 100 nm or less;
• an aspect ratio (maximum width/thickness in particles) of the sheet-like particles of the zeolite is 100 or more;
• the solvent contained in a whole system in the formation of the hyper-swollen lamellar phase is a mixed solvent containing a hydrocarbon solvent and water, wherein the whole system in the formation of the hyper-swollen lamellar phase means any components which are mixed in order to form the super-swollen lamellar phase and include solutes and solvents;
• and
• a mass ratio of the hydrocarbon-containing solvent and water in the mixed solvent is 85:15 to 99.99:0.01.
