Abstract A one-pot strategy was developed to coat micro- and nanomaterials with crystalline nanoparticles. Three Li-based materials were coated by a solution combustion synthesis method. By this procedure, we obtained LiCoO2 nanoparticles covered with nanocrystals of NiO and Ag; LiMn2O4 nanoparticles covered with Ag, and LiNi0·5Mn1·5O4 microparticles covered with ZnO. The results confirm that the coating of the nano- and micro-particles was successful. The materials obtained were characterized morphologically and structurally. Using X-ray diffraction, Transmission Electron Microscopy (TEM), Scanning Electron Microscope (SEM), and Energy-dispersive X-ray Spectroscopy Mapping, the morphological uniformity and high crystallinity of the nano-coatings were confirmed. Therefore, this method makes it possible to obtain different coatings by varying the weight percentage of the coating material, yielding homogeneously coated materials, even at percentages as low as 0.5 wt%. The developed method has great advantages as it is simple, inexpensive, and easily scalable.

微米和纳米粒子的纳米晶涂层的一锅法

摘要 开发了一种用结晶纳米粒子涂覆微米和纳米材料的一锅策略。采用溶液燃烧合成法对三种锂基材料进行包覆。通过该程序，我们获得了覆盖有 NiO 和 Ag 纳米晶体的 LiCoO2 纳米颗粒；包覆Ag的LiMn2O4纳米粒子和包覆ZnO的LiNi0·5Mn1·5O4微粒。结果证实纳米颗粒和微米颗粒的包覆是成功的。获得的材料在形态和结构上进行了表征。使用 X 射线衍射、透射电子显微镜 (TEM)、扫描电子显微镜 (SEM) 和能量色散 X 射线光谱图，证实了纳米涂层的形态均匀性和高结晶度。所以，这种方法可以通过改变涂层材料的重量百分比来获得不同的涂层，从而产生均匀的涂层材料，即使百分比低至 0.5 重量％。所开发的方法具有很大的优势，因为它简单、便宜且易于扩展。
