Nanoheterostructures based on titanium, vanadium, molybdenum, and tungsten oxides assembled in the form of microspheres have been synthesized. Their structural and photoelectronic properties have been studied. It has been shown that the photocatalysis rate increases significantly for microspheres consisting several metal oxides. A relation of the photocatalysis rate to the number of V⁴⁺ paramagnetic centers and the time of their relaxation after the end of illumination has been revealed. It has been found that the spatial separation of photoexcited charge carriers between different nano-oxides in heterostructures leads to the accumulation of charge in them and to prolonged catalysis. Consequently, they are promising for application as the main material of photocatalytic filters for cleaning the environment.

已经合成了以微球形式组装的基于钛，钒，钼和氧化钨的纳米异质结构。已经研究了它们的结构和光电性能。已经表明，由几种金属氧化物组成的微球的光催化速率显着提高。已经揭示了光催化速率与V ⁴⁺顺磁性中心的数目以及照明结束后它们的弛豫时间的关系。已经发现，异质结构中的不同纳米氧化物之间的光激发电荷载体的空间分离导致电荷在其中的积累并延长了催化作用。因此，它们有望用作清洁环境的光催化过滤器的主要材料。
