Pulsed Plasma-Chemical Synthesis of CuxOy-TiO2 Nanocomposite

The CuxOy-TiO2 nanocomposite was synthesized by a pulsed plasma-chemical method. Pulsed plasma-chemical synthesis was performed using a laboratory bench, which included a TEA-500 pulsed electron accelerator and a reaction chamber. The structure of the composite was studied by X-ray phase analysis and transmission electron microscopy. The dependence of the geometric mean size, morphology, and phase composition of the composite on the molar ratio of reagents in the initial mixture, such as a reaction chamber, was confirmed. The morphology of the particles of the CuxOy-TiO2 nanocomposite with the core/shell structure changed into spherical particles with a uniform porous structure. The phase composition with a predominant rutile phase transformed to a mixture of several crystalline phases (anatase, rutile, copper chloride).
