Formation features of zink titanate by electric explosion dispersion of titanium and zinc wires in an oxygen-containing atmosphere

In present work, we have synthesized, for the first time, zinc titanate nanoparticles by electric explosion of titanium and zinc wires in an oxygen-containing atmosphere (argon - oxygen 20 vol. %). As-synthesized nanoparticles nanoparticles were characterized using transmission electron microscopy, X-ray analysis, and X-ray photoelectron spectroscopy. The particles have a spherical shape and an average particle size of 82 nm. The phase composition is presented by zinc titanate and a small amount of titanium oxide, which corresponds to the phase diagram of the TiO₂-ZnO system. The photocatalytic activity of the synthesized nanoparticles was studied in the decomposition reaction of a model dye methylene blue and it was found that it was higher than that of titanium oxide nanoparticles obtained by electric explosion of a titanium wire in an oxygen-containing atmosphere. In addition, the synthesized nanoparticles demonstrated high antibacterial activity against MRSA bacteria.
