Abstract: Method of electric arc synthesis of composite microparticles metal-semiconductor-dielectric based on titanium, titanium nitride and rutile with productivity up to 10 g/min is proposed. Using diffraction and microscopic methods, the morphology and structural-phase composition of the synthesized microparticles were studied. Using the example of methylene blue degradation, the photocatalytic activity of synthesized microparticles in the visible radiation range was demonstrated and its possible mechanism was proposed.

Keywords: titanium, rutile, titanium nitride, microparticles, photocatalysis, visible light.
