Some Physicochemical Aspects of the Preparatory Stages in the Formation of Self-cleaning Photocatalytic Active Coatings for Building Construction Materials

Abstract

A complex systematic study of the interaction of structural components in cerium subgroup lanthanide nitrate systems and representatives of the IA group (Li, Na, K) of the elements of the periodic system, precursors of modern multicomponent oxide multifunctional materials based on them, established the formation of a representative class of alkaline coordination nitrates Ln. Their composition, formation conditions, atomic-crystalline structure, forms of Ln coordination polyhedral, types of ligand coordination, a number of their properties were studied using a complex of physicochemical methods: chemical, X-ray phase, X-ray structural, IR-spectroscopic, crystal-optical, thermographic, and SHG laser radiation. The data obtained are the basis for identifying and monitoring the phase state of processing facilities in the preparatory stages when forming self-cleaning coating layers of building construction materials by using innovative technologies; using nanostructured composite systems of lanthanides and transition elements with photocatalytically active and hydrophilic properties; various combined methods of their activation; and establishing technological and functional dependencies to modify the properties of the products obtained.
