Gold nanparticles reduce toxic waste from petroleum products

Perfumes, paints and cosmetics could be manufactured without producing so much toxic waste. Before petroleum hydrocarbons can be turned into useful household chemicals they have to be oxidized, a process that often relies on heavy-metal oxidants such as manganese or chromium compounds which create toxic waste. Now researchers at Cardiff University, UK, have oxidized perfume using a catalyst made from gold nanoparticles. more @ newscientist.com
