The novel catalyst, created using single or few palladium atoms, has demonstrated the ability to remove methane from natural gas engine exhaust at temperatures less than 350° Celsius while maintaining ...

A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the ...

Three-way catalysts serve as the cornerstone of modern vehicular exhaust after-treatment by simultaneously oxidising carbon monoxide and hydrocarbons while reducing nitrogen oxides in a single ...

A gasoline engine’s dirtiest moment lasts only a few seconds. In the time between ignition and the catalytic converter reaching its working temperature, a car can emit more hydrocarbons and carbon ...

Preparing catalysts by sending hot, steamy car exhaust over them could improve their efficiency and reduce the amount of rare and expensive metals required in vehicle catalytic converters and many ...
