We aim for clarification of fundamental scientific questions and solving technical issues which impede broad utilization of photoactive materials (e.g. nanocrystalline titanium dioxide). These materials can be used for self-cleaning surfaces, photocatalytic purification of air, water and contaminated soil, organic synthesis, utilization of solar energy etc. Our Laboratory of Photocatalytic Materials and Technologies in Technopark Kralupy offers highly qualified services for research, development and inovation, and experimental work for various customers.
OUR MAIN TOPICS?
- Preparation of layers of semiconductor materials (e.g. titanium dioxide, tungsten oxide, iron oxide) using various chemical and physico-chemical procedures.
- Development of semiconductor materials for photoelectrochemical water splitting using sunlight.
- Study of photocatalytic processes for sunlight energy coversion to eletrical energy.
- Development of standard methods (ISO, CEN) for testing of selfcleaning and disinfection effects of photocatalytic surfaces.
- Construction of various types of laboratory photoreactors for photocatalytic cleaning and disinfecting in liquid and gaseous phase and their testing in order to optimize the working conditions.
- Study of the kinetics of oxidative degradation of organic pollutants and photocatalytic inactivation of microorganisms.
