The laboratory of nanostructure materials does research in the area of preparation and optimization of the preparation of different types of nanostructure materials such as metal oxides or carbon materials, in different macroscopic forms, especially for photocatalytic and catalytic decomposition of organic pollutants in the environment and photocatalytic reduction of greenhouse gases. Nanostructure powder, thin layers or monoliths are prepared not only with the use of conventional methods, but new unconventional preparation and processing methods are also developed and optimized, e.g. using supercritical and subcritical fluids. Preparation processes and their optimization are investigated on the basic research level, focusing on the influence of individual preparation or processing steps or of the feedstock/chemical precursor on the physicochemical properties of the prepared material and, consequently, on photocatalytic or catalytic efficiency. Our laboratory also uses microwave pyrolysis to prepare carbon sorbents, which are then characterised with the use of physisorption. We focus on inter-disciplinary research, using knowledge and information from material engineering, inorganic chemistry, physical chemistry, solid state physics, photochemistry, organic technology, as well as environmental and chemical engineering.
