Oxides of nitrogen (NOx) emitted by internal combustion engines represent a major challenge for urban air quality and global climate targets. In lean‐burn and diesel engines, the excess oxygen in the ...

A new, patented catalyst developed by scientists at the U.S. Department of Energy's Argonne National Laboratory that can cut 95 to 100 percent of the nitrogen oxide (NOx) emissions from diesel engines ...

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions ...

CCJ recently got an up-close first look at Cummins' new X15 diesel engine, the powerhouse built on the innovative HELM platform to conquer strict 2027 emissions regulations. Emission innovation ...

A research team has developed a new strategy to improve catalysts used to remove nitrogen oxides from industrial emissions. By using ethanol during catalyst preparation, the scientists significantly ...

Three-way catalysts constitute the cornerstone of gasoline engine exhaust treatment, achieving simultaneous oxidation of carbon monoxide and unburnt hydrocarbons alongside reduction of nitrogen oxides ...

Car owners sometimes find, to their dismay, that their catalytic converters have been stolen because of the platinum inside. How much platinum is that, anyway?

Israel Wachs is G. Whitney Snyder Professor of Chemical and Biomolecular Engineering at Lehigh University and director of its Operando Molecular Spectroscopy and Catalysis Research Lab. When power ...
