Patent ID: 8445063

Claim:
A process for making a metal oxide coated substrate for use in removing contaminants from fluid streams, the process comprising: a. contacting a metal salt with a first aqueous solvent to form a metal salt mixture, wherein the ratio of solvent to metal salt is from 20:1 to 1:20 by weight; b. reacting a sufficient amount of the metal salt mixture with an amount of metal powder in a zero valence state at ambient conditions to initiate an oxidizing reaction between the metal powder and the metal salt mixture to form an oxidizing mixture; c. contacting the metal powder and metal salt mixture with a substrate, wherein the ratio of metal powder to substrate is less than 12:1; and, d. optionally adding a sufficient amount of a second solvent to moisten the substrate and adhere an oxidizing metal oxide composition onto the substrate wherein the oxidizing reaction substantially proceeds forming a uniformly, metal oxide coated substrate comprising from at least 5% to more than 95% by weight metal oxide for use in removing contaminants from fluid streams.
