Nanotube catalysts improve industrial reaction
Abstract:
A catalyst consisting of modified carbon nanotubes makes an important industrial reaction milder, safer and more selective, according to researchers in Germany.
Dangsheng Su and chemists at the Fritz Haber Institute of the Max Planck Society, Berlin, found that by oxidising the surface of carbon nanotubes and adding a dash of phosphorous, they created stable catalysts that could oxidatively strip hydrogen from butane gas more selectively, and under milder reaction conditions, than the complex metals usually employed. The reaction is used to make 4-carbon alkenes including butadiene - a feedstock chemical for several useful polymers such as synthetic rubber and plastic.
