研究了氧化铝负载Pt纳米颗粒的形貌（尺寸和形状）与C3H6贫燃还原NO催化性能之间的关系。据透露，约12 nm的主要立方铂纳米晶体的低指数方面的转换到更高的指数平面，发生在反应条件下，与反应产物的催化活性和选择性的实质性变化。
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.
