The present work is focused on the understanding of the CeO₂ support interactions with cyclodextrin‐stabilized palladium nanoparticles (PdNPs) and the effect in the Suzuki‐Miyaura reaction outcome. Mostly, it is evidenced the strong influence of the cyclodextrin torus on the reactivity of PdNPs towards the ceria matrix. Structural characterization by X‐rays photoelectron spectroscopy (XPS) Raman spectroscopy, diffuse reflectance spectroscopy (DRS) and powder X‐rays diffraction (XRD, via Rietveld refinement) afforded to infer that palladium is being partially brought into the CeO₂ structure. Transmission electron microscopies (TEM and STEM) visualizations allowed to evidence a bimodal size distribution of PdNPs (1–5 nm and 20–100 nm) over the catalysts even though particles up to 5 nm are probably the most responsible for the catalytic results reported herein.

二氧化铈上的环糊精稳定的钯纳米粒子：Suzuki-Miyaura反应中支持相互作用和关键促进作用的研究

目前的工作集中在对CeO ₂支持物与环糊精稳定的钯纳米粒子（PdNPs）的相互作用及其对Suzuki-Miyaura反应结果的影响的理解上。大多数情况下，已证明环糊精环面对PdNP对二氧化铈基质的反应性有很强的影响。通过X射线光电子能谱（XPS）的结构表征，拉曼光谱，漫反射光谱（DRS）和粉末X射线衍射（XRD，通过Rietveld精制）可以推断出钯已部分引入CeO _2中结构体。透射电子显微镜（TEM和STEM）可视化可以证明PdNPs在催化剂上的双峰尺寸分布（1-5 nm和20-100 nm），即使最大5 nm的颗粒可能是本文报道的催化结果最主要的原因。
