Description:

The health effects of indoor air pollution are important because individuals spend large fractions of their time in indoor environments and frequently have little control over exposure time or indoor air quality (IAQ). Cost-effective technologies are particularly needed for air cleaners with improved ability to remove carbon monoxide and selected volatile organic compounds (VOCs) from indoor air systems, for which conventional technology is inadequate.

The proposed research project will establish the technical and economic feasibility of a photocatalytic Adsorption-Integrated-Reaction (AIR) technology, providing a system to destroy VOCs and other indoor air contaminants at ambient temperatures, with compact units, and at low cost. To accomplish this objective, the indoor AIR technology employs a new, multicomponent photocatalyst, which is much more active than traditional titania photocatalysts for dilute concentrations of contaminants in air. The program will use experimental studies of destruction efficiency on representative classes of VOCs, catalyst synthesis studies to identify the important multicomponent catalyst variables, and a competitive technology evaluation for a comparison of the Phase I technology relative to other alternatives. It is anticipated that an effective IAQ control concept will be demonstrated that will provide a cost-effective technology for cleaning VOCs and other contaminants from indoor air systems.

The commercial applications for the concept will be for control of indoor air pollution by destruction of carbon monoxide, VOCs, and, ultimately, microorganisms in indoor ventilation air, for both government facilities and worldwide commercial and industrial sites. The technology will reduce indoor air pollution control costs, improve indoor air quality, and increase industrial and commercial productivity, thus enhancing economic competitiveness.
