摘要：
The relationship between the morphology (size and shape) of alumina supported Pt nanoparticles; and catalytic behaviour for lean reduction of NO with C3H6 is investigated. It is revealed that the conversion of the low index facets of the mainly cubic Pt nanocrystals of around 12 nm to higher index planes, taking place under reaction conditions, is associated with substantial changes in the catalytic activity and selectivity to reaction products.
