摘要：
The effects of temperature and atmosphere on the coarsening of Pt particles in a model NOx trap (Pt/BaO/Al2O3) were examined by XRD, TEM, and CO chemisorption. The main finding, that the most significant particle growth occurs at elevated temperatures under oxidizing conditions, is relevant to NOx trap durability.
