The object of the research is nano- and micro-sized simple and complex oxides,
their composites and nanomaterials based on layered silicates.
The purpose of the work is to obtain the latest adsorption and catalytic materials
based on nano- and micro-sized oxides, their composites and using natural mineral
raw materials (layered silicates, volcanic glass) with adjustable morphology,
structure and physicochemical properties.
Research methods are scanning and transmission electron microscopy, X-ray phase
analysis, infrared spectroscopy, low-temperature nitrogen adsorption-desorption,
complex thermal analysis, atomic emission spectrometry method with inductively
coupled plasma.
Photocatalysts based on pure titanium(IV) and zinc(II) oxides and composites were
obtained. The technological parameters of the processes of obtaining materials,
their morphology, phase composition and features of the porous structure were
studied. The kinetic dependences of the adsorption and photocatalytic activity of
the synthesized samples were studied on the example of wastewater treatment
contaminated with a wide range of organic substances, in particular, synthetic dyes
and pharmacological drugs. An act of implementation was received at the LLC
"Fluid Management System" enterprise on the effective action of the photocatalyst
based on modified titanium (IV) oxide, which was used to purify colored industrial
wastewater from the color caused by the content of dyes. Based on the
experimental data, a technological scheme for the production of zinc(II) oxide was
proposed.
The main regularities of the processes of obtaining composite materials based on
natural silicates and zero valent iron were established. Their structural and sorption
characteristics and physical and chemical properties were studied.
