Abstract:
The formation of titanium nanoparticles (NPs) in a high-voltage electric discharge between titanium electrodes in liquid xenon at a temperature of –105$^{\circ}$C has been observed. It has been shown that these titanium nanoparticles have a spherical shape with an average diameter of $<$ 50 nm and they possess high chemical activity. This makes it possible when a relative mass concentration of NP reaches $\sim$10$^{-6}$ to efficiently purify xenon from electronegative impurities for its use as a working medium for a new generation of high-efficiency nuclear radiation detectors.
