Abstract: A polymer-catalyst assembly includes polarized polymeric nanofibers retaining a plurality of catalytic metallic nanoparticles. A method of making the polarized polymer-catalyst assembly may include providing a fiber mat having polymeric nanofibers retaining a plurality of catalytic metallic nanoparticles, stretching the fiber mat in a uniaxial direction, simultaneous with the step of stretching, thermally heating the fiber mat, simultaneous with the steps of stretching and thermally heating, subjecting the fiber mat to an electric field, whereby the simultaneous steps of stretching, thermally heating, and subjecting thereby form a polarized fiber mat.

Abstract: A process for producing a zeolite membrane composite includes a step of obtaining FAU-type seed crystals, a step of depositing the FAU-type seed crystals on a support, a step of forming an AFX-type zeolite membrane on the support by immersing the support in a raw material solution and growing an AFX-type zeolite from the FAU-type seed crystals by hydrothermal synthesis, and a step of removing a structure-directing agent from the AFX-type zeolite membrane. In this way, the AFX-type zeolite membrane can be provided.
