Inexpensive oxidation catalyst could reduce diesel emissions

It's not a new material, but a new application of silver hollandite could make a big impact in diesel emissions control. Researchers at Pacific Northwest National Laboratory have developed an inexpensive method of synthesizing nano-sized silver hollandite and have found the material has unique catalytic properties that can completely oxidize nitrogens of oxide, carbon monoxide and hydrocarbons. These chemical reactions caused by the silver hollandite are key to reducing pollutants in diesel engine emissions.
