New technology promises better catalytic converter

A novel design for a catalytic converter disperses nanoparticles of the catalytic noble metal platinum on nanowires and then sheaths the wires is a layer of silica pierced with holes. The silica prevents the platinum catalyst from aggregating, while the pores allow gases to reach the platinum catalyst. The design might one day reduce the amount of platinum needed to  detoxify exhaust gases.
