Abstract: The method of electric arc synthesis of photoactive multicomponent composite microparticles on the example of a ZnO/TiO$_2$/Nb$_2$O$_5$ system using a low-temperature plasma generator is proposed. Morphology and structural-phase composition of synthesized composite microparticles have been studied. Sold monstrated their record high photocatalytic activity (rate constant 128.6 $\cdot$ 10$^{-3}$ min$^{-1}$) combined irradiation with ultraviolet and visible light.

Keywords: titanium, zinc oxide, niobium, microparticles, photocatalysis, microscopy, morphology, structure.
