ABSTRACT BiPO4/BiVO4 nanocrystalline composites were synthesized under hydrothermal conditions. The influence of the initial composition of the system on the phase state, the size of crystallites, and the morphology of the formed particles was determined. The photocatalytic activity of the nanocomposite was studied using the decomposition of methyl violet as an example.

[In Russian] Влияние состава системы BiPO4/BiVO4 на фазообразование, морфологию и свойства нанокристаллических композитов, полученных в гидротермальных условиях
АННОТАЦИЯ Нанокристаллические композиты BiPO4/BiVO4 синтезированы в гидротермальных условиях. Определено влияние исходного состава системы на фазовое состояние, размер кристаллитов и морфологию образующихся частиц. На примере разложения метилового фиолетового изучена фотокаталитическая активность нанокомпозита.
