Description
Summary:The photocatalytic properties of layered semiconductors, namely KNb 3 O 8 , and a product of its acid treatment, namely K 3 H 3 Nb 10.8 O 30 in the reduction reaction of silver ions with the formation of the corresponding metal-semiconductor nanostructures are established. Electron microscopy has shown that silver nanoparticles are deposited mainly on the edges of niobate rods and plates when potassium niobate suspensions are irradiated with UV light in the presence of AgNO 3 . Silver nanoparticles of 10-30 nm are formed when K 3 H 3 Nb 10.8 O 30 is used as a photocatalyst; they are deposited on the niobate surface and practically do not have a surface plasmon resonance band in the visible range of the spectrum, which may be associated with the formation of Ag 2 O on the surface of silver nanoparticles or the formation of their chain aggregates.
