Abstract
Disclosed is a method for producing a pigmented composite comprising contacting a microporous material with a tin compound to form a composite then contacting the composite with a pigment comprising an elemental metal, a metal oxide, a metal alloy, a metal salt, or a combination thereof to produce the pigmented composite. The pigmented composites described herein are useful for separating one or more analytes present in a fluid sample.
Claims29
A method for producing a pigmented composite, comprising:
- a. contacting a microporous material with an aqueous solution of a tin compound to produce a first composite, wherein the microporous material comprises a ceramic, a metal, metal oxide, carbon, or glass;
- and
- b. contacting the first composite with an aqueous solution of a first pigment comprising a palladium compound followed by contacting the first composite with an aqueous solution of a second pigment comprising a nickel compound to produce the pigmented composite.
A method for producing a pigmented composite, comprising:
- a. contacting a microporous material with an aqueous solution of a tin compound to produce a first composite, wherein the microporous material comprises aluminum oxide that is electrochemically formed or etched, or aluminum or titanium that has been anodized, and
- b. contacting the first composite with an aqueous solution of a pigment comprising an elemental metal, a metal oxide, a metal alloy, a metal salt, or a combination thereof to produce the pigmented composite.
