Optalys: a new generation of materials in automotive catalytic converters
The perfecting of a new range of catalytic supports for the reduction of exhaust gas emissions from petrol engines, with a cerium and zirconium mixed oxide based composition doped by rare earth ions, makes it possible to significantly increase the durability and efficiency of catalysts.
These porous supports definitely have a better performance than the first generation supports thanks to a bigger pore space with an increased thermal stability and a capacity to release or absorb oxygen improved by 25%.
Moreover, it seems possible to apply this technology to diesel engines.
