Researchers show method to remove greenhouse gas from natural gas engine exhaust.
It has long been trying to reversibly change the active structures of supported metal catalysts in response to dynamic operating conditions. Researchers have found that at low temperatures, individual palladium atoms bonded to a catalyst’s surface may remove 90% of unburned methane from natural-gas engine exhaust.
This development in single-atom catalysis may help to reduce methane exhaust emissions, one of the worst greenhouse gases that trap heat at a rate around 25 times that of carbon dioxide. Methane is one of the worst greenhouse gases.
Researchers from Washington State University and the Department of Energy’s SLAC National Accelerator Laboratory demonstrated that the catalyst removed methane from engine exhaust at lower temperatures where engines start up and higher temperatures where they operate most effectively but where catalysts frequently fail.
