Catalyst Turns Nitrate Pollution into Water and Nitrogen

HOUSTON TX

Researchers at Rice University, US, have developed a nanoparticle catalyst that converts hazardous nitrate contamination in water into more water and nitrogen gas. Nitrates enter water supplies largely through agricultural runoff, and the problem is thought to be getting worse due to land-use changes. As well as causing environmental problems through eutrophication, nitrates are toxic to babies and pregnant women and may also be carcinogenic.
