Abstract
A method for making a functional structural body includes a skeletal body of a porous structure composed of a zeolite-type compound, and at least one type of metallic nanoparticles present in the skeletal body, the skeletal body having channels connecting with each other, the metallic nanoparticles being present at least in the channels of the skeletal body.
Claims5
A method for making a functional structural body, comprising:
- a calcination step of calcinating a precursor material (B) obtained by impregnating a precursor material (A) for obtaining a skeletal body of a porous structure composed of a zeolite-type compound with a metal containing solution;
- a hydrothermal treatment step of hydrothermally treating a precursor material (C) obtained by calcinating the precursor material (B) to obtain the functional structural body;
- and
- a step of subjecting the hydrothermally treated precursor material (C) to a reduction treatment,
- wherein the zeolite-type compound is selected from FAU type, MTW type, MFI type, FER type, LTA type, MWW type, MOR type, LTL type, and BEA type,
- wherein the precursor material (A) is a regular mesopore material, and wherein the regular mesopore material is a compound including a Si—O skeletal body in which pores are uniformly sized and regularly developed one-dimensionally, two-dimensionally, or three-dimensionally.
