Removing volatile organic compounds from air.(FILTERS)

Advanced Ceramics Report, May, 2007

Japanese researchers have used porous manganese oxide garnished with gold nanoparticles to remove volatile organic compounds (VOCs) from air and break them down.

Most modern air-purification systems are based on photocatalysts, adsorbents such as activated charcoal, or ozonolysis. However, these conventional systems are not particularly good at breaking down organic pollutants at room temperature. Now, researchers lead by Anil K Sinha at the Toyota Central R & D (research and development) Labs, have developed a new material that effectively removes VOCs as well as nitrogen- and sulfur oxides from air at room temperature. The system involves a highly porous manganese oxide with gold nanoparticles grown into it.

To prove the effectiveness of their new...
