Mazda Develops a World-First Catalyst for Autos Using Nanotechnology

On Monday Mazda was announced that developed the world first car catalyst using nano-technology. It claimed that reduced the use of platinum and palladium by 70% or more. Honestly I'm no idea any impact on catalyst pricing and I'm not the fans of catalyst modification (I'm environmentalist ). However the platinum stock price was dropped rapidly after such announcement.
