摘要

本工作介绍了多脉冲电子束和反应混合物的额外加热对通过脉冲等离子体化学方法制备的CuxOy/TiO2纳米复合材料的结构和形态特征的影响的研究结果。通过透射电子显微镜（TEM）、能量色散X射线分析（EDX）和X射线衍射（XRD）对CuxOy/TiO2纳米复合材料进行了表征。发现脉冲电子束对合成的复合材料的冲击增加会影响其团聚程度和几何平均粒径。反应混合物的额外加热增加了合成颗粒的几何直径（高达200nm）。CuxOy/TiO2纳米复合材料的相组成根据合成条件而变化。

Effect of conditions of the pulsed plasma-chemical synthesis on physicochemical properties of the CuxOy/TiO2 nanocomposite

This work presents the results of study on the effect of multi-pulse electron beam and additional heating of the reaction mixture on the structural and morphological characteristics of the CuxOy/TiO2 nanocomposite prepared by the pulsed plasma-chemical method. The CuxOy/TiO2 nanocomposites were characterized by transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), and X-ray diffraction (XRD). It was found that an increase in the impact of a pulsed electron beam on the synthesized composite affected the degree of its agglomeration and the geometric mean particle diameter. Additional heating of the reaction mixture increased the geometric diameter of the synthesized particles (up to 200 nm). The phase composition of the CuxOy/TiO2 nanocomposite changed depending on the synthesis conditions.
