New materials for heterogeneous catalysis and photocatalysis based on synthetic titanosilicate analogues of the Khibiny Mountain’s minerals
The prospect of using synthetic titanosilicate as a material for the area of photo and heterogeneous catalysis was indicated. Photocatalytic activity of analogues of natural minerals lintisite, ivanyukite, zorite, korobitsynite, sitinakite was investigated towards the solution of ferroin in the visible part of light with λ = 546 nm. It was determined that the highest degree of destruction of the organic indicator had a mixture of IONSIVE-IE, ETS-4 and SIV (68.72 %), as well as a synthetic analogues of ivanyukite SIV (42.63 %) and korobitsynite SKR (31.48 %). It was shown that it is possible to obtain a promising, rare, heterogeneous catalyst for organic synthesis on the basis of titanosilicate AM-4 after its treatment by an acid solution and the transformation of the AM-4 crystal structure to the SL3 compound.
