Metal Oxide Nanomaterials for Ecological Purpose – SnO2 Nanostructures as Sensitive Material
Metal oxide nanomaterials have unique properties that allow for numerous applications and uses in industry and consumer products. However, these materials also potentially pose a risk to humans, aquatic and terrestrial organisms, and the environment. This presentation will address the following topics: the features of the properties and creation of metal oxide nanomaterials, in particular TiO2, ZrO2, SnO2 and their applications for ecology; crystallochemical characteristic, the surface structure and surface phenomena of the selected metal oxides in the water and at the air; synthesis methods of metal oxide nanomaterials and ways for creation of nanocomposites on their basis and methods for obtaining individual nanoparticles of metal oxides with certain properties; the prospects for the production of metal oxide nanocomposites and their application for environmental applications. The establishment of technological features of tin (IV) oxide nanostructures of various morphologies, their synthesis and the study of their physical and chemical properties for further use as sensitive materials for metal oxide chemoresistive gas sensors will also be presented.
