Abstract
Official abstract text for this publication.
A metal-supported nonwoven fabric is provided which enables effective synthesis of a target product when used as a catalyst in a flow reaction. The metal-supported nonwoven fabric comprises a nonwoven fabric containing polyolefin fibers or PET fibers, and metal particles. The nonwoven fabric has grafted side chains bound thereto formed of polyvinylpyrrolidone, polyacrylic acid, or a polymer containing functional groups with unshared electron pairs. The metal particles are supported by the grafted side chains via pyrrolidone groups of the polyvinylpyrrolidone, carboxy groups of the polyacrylic acid, or the functional groups with unshared electron pairs.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metal-supported nonwoven fabric comprising: a nonwoven fabric containing polyolefin fibers or PET fibers; and metal particles, the nonwoven fabric having grafted side chains bound thereto formed of polyvinylpyrrolidone, the metal particles being supported by the grafted side chains via pyrrolidone groups of the polyvinylpyrrolidone, wherein the metal particles has a metal of Pd, Pt, Au, Ag, Rh, Ru, Ir, Os, Cu, Ni, or an alloy containing at least one of those metals. 2. The metal-supported nonwoven fabric according to claim 1 , wherein the metal particles have an average particle size (D 50 ) of 100 nm or less. 3. The metal-supported nonwoven fabric according to claim 1 , wherein the grafted side chains bound to the nonwoven fabric is in an amount of 10 to 200 parts by mass relative to 100 parts by mass of the nonwoven fabric.
