Polyoxometalate Fabric Catalysts for Air Purification


Self-deodorizing inorganic-organic fiber that is polyoxometalate-modified that can be used to remove a contaminant such as a gaseous toxic or malodorous compound from the air.

Technical Summary

Decreasing the potential danger of toxic gases has long been a significant issue.  Offensive odors originating from cigarette smoke, sweat, exhaust gases, and rotten food in the workplace, the home and elsewhere are caused by thousands of gaseous components.  Examples of deleterious and/or foul-smelling compounds include, but are not limited to acetaldehyde, hydrogen sulfide, methyl mercaptan, ammonia, trimethylamine and nicotine.  Japan is currently developing a sizable textile industry whose goal is to formulate a method for eliminating such odors from various types of fabrics.

Dr. Hill's group has developed new materials with catalytic activity that show promise as self-deodorizing inorganic-organic fiber or cloth materials.  The goal of this technology is to fabricate and use self-deodorizing fabrics in the form of clothing, furniture upholstery, curtains or carpets in order to remove or degrade gaseous toxic and/or malodorous compounds in the home and work environments.  This technology is superior to that being developed in Japan because that technology is stoichiometric and not catalytic.  Catalytic activity allows for aerobic oxidation of gaseous molecules.
