In order to further reduce the emissions of nitrogen oxides causing the emission of exhaust gases from diesel engines, a group of researchers has discovered a new reaction mechanism that could be used to improve catalyst design of pollution control systems.
The research focuses on a type of catalyst called zeolites.
The zeolites have a crystalline structure that contains tiny pores approximately one nanometer in diameter. As one of the authors of this finding explains, Rajamani Gounder, Professor of Chemical Engineering at the School of Chemical Engineering at Purdue University in Indiana, an essential property of the catalyst has been discovered to be able to convert nitrogen oxides.
The study, published in Science, also has as author William Schneider, Professor of Engineering at the University of Notre Dame, also in Indiana, who has stated:
The results here point to a previously unknown catalytic mechanism and also point to new directions to discover better catalysts. This is a reaction of great environmental importance used to clean the exhaust gases.
