US 6,713,076 B1 · Methods for removing a contaminant by a polyoxometalate-modified fabric or a polyoxometalate-modified cellulosic fiber and fabrics thereof

Abstract

The invention relates to a method for removing a contaminant from a gas phase or a liquid phase by contacting an article composed of (1) a fabric or cellulosic fiber and (2) a polyoxometalate, wherein the polyoxometalate is incorporated in the fabric or cellulosic fiber, with the gas phase or liquid phase containing the contaminant. The invention further relates to a polyoxometalate-modified fabric composed of a fabric and a polyoxometalate of the present invention incorporated in the fabric. The invention further relates to an article containing the polyoxometalate-modified fabric. The invention further relates to a method for making the polyoxometalate-modified fabric, by contacting the fabric with a polyoxometalate to produce a polyoxometalate-modified fabric.

Claims6

Dependent claims

A polyoxometalate-modified fabric, comprising a fabric and a polyoxometalate incorporated into the fabric, said polyoxometalate having the formula [Y VxZ12-xO40] [A], wherein Y is phosphorus, silicon, or aluminum;

Z is tungsten or molybdenum;
x is from 1 to 6, and A is a counterion, with the proviso that when the fabric is carbon cloth, the polyoxometalate is not H5PV2Mo10O40.
