Rice U.'s one-step catalyst turns nitrates into water and air

Engineers at Rice University’s Nanotechnology Enabled Water Treatment (NEWT) Center have found a catalyst that cleans toxic nitrates from drinking water by converting them into air and water.

The research is available online in the American Chemical Society journal ACS Catalysis.

“Nitrates come mainly from agricultural runoff, which affects farming communities all over the world,” said Rice chemical engineer Michael Wong, the lead scientist on the study. “Nitrates are both an environmental problem and health problem because they’re toxic. There are ion-exchange filters that can remove them from water, but these need to be flushed every few months to reuse them, and when that happens, the flushed water just returns a concentrated dose of nitrates right back into the water supply.”

Wong’s lab specializes in developing nanoparticle-based catalysts, submicroscopic bits of metal that speed up chemical reactions. In 2013, his group showed that tiny gold spheres dotted with specks of palladium could break apart nitrites, the more toxic chemical cousins of nitrates.
