Diesel Know-How: How New Diesel Engines Emit Little Greenhouse Gas Nitrous Oxide #greenbuilding

The latest catalytic converters reduce pollution by unusual mechanism RICHLAND, Wash. — The newest catalytic converters in diesel engines blast away a pollutant from combustion with the help of ammonia. Common in European cars, the engines exhaust harmless nitrogen and water. How they do this hasn’t been entirely clear. Now, new research shows that the catalyst attacks its target pollutant in an unusual way, providing insight into how to make the best catalytic converters. This computer model of a zeolite catalyst shows nitric oxide (ball-and-stick) interacting with a positively charged copper ion (copper ball) at an unexpected angle (red dotted lines). Credit: Kwak at al 2013/PNNL Reporting in the journal Angewandte Chemie International Edition , a team of researchers in the Janos Szanyi led by chemist Janos Szanyi showed that the artificial catalyst works much the same w...
