通过区域选择性原子层沉积（ALD）将Pt纳米颗粒（NPs）封装在氧化锆纳米笼中可以显著提高Pt的稳定性和活性。这种包封的Pt NP显示出比商业Pt/C催化剂高10倍的稳定性和比Pt/C高6.4倍的氧还原反应（ORR）活性。[图形]。
Encapsulation of Pt nanoparticles (NPs) in a zirconia nanocage by area-selective atomic layer deposition (ALD) can significantly enhance both the Pt stability and activity. Such encapsulated Pt NPs show 10 times more stability than commercial Pt/C catalysts and an oxygen reduction reaction (ORR) activity 6.4 times greater than that of Pt/C.[GRAPHICS].
