Obtaining modified alkaline titanosilicate by hydrothermal synthesis

Abstract

Alkaline titanosilicate (Ti-Si) with the structure similar to the mineral ivanyukite was obtained by hydrothermal synthesis. The effect on the phase composition and properties of the obtained product of preliminary addition to the titanosilicate precursor before the synthesis of a niobium-containing modifier was revealed. The sorption and photocatalytic properties of the synthesized samples were determined and it was shown that the presence of niobium in the Ti-Si structure significantly increases its ability to decompose organic dyes, in particular methyl blue, even in visible light.
