Porous manganese oxide garnished with gold nanoparticles removes volatile organic compounds from air and breaks them down

04-Apr-2007

In addition to nitrogen oxides and sulfur oxides, many volatile organic compounds (VOCs) in air contribute to smog and high ozone levels, as well as potentially damaging human health. Clean-air laws are thus rightly continuing to become stricter. Most modern air-purification systems are based on ...
