Photocatalytic Materials and Processes

Current main lines of research encompass the synthesis of the photoactive materials, their testing in terms of photocatalytic activity and properties to clarify fundamental scientific questions and subsequently solving technical problems that still stand in wide practical application of photoactive materials. 

Such applications are the self-cleaning surfaces (glass, tile, paint, concrete and textiles); photocatalytic purification of air, water and contaminated soils; organic synthesis; fuel (hydrogen) production via light assisted water electrolysis; the use of solar energy and its application in other potential fields.

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 and industrial partners. At present, easy-cleaning surfaces and photocatalytic purification of air represent the main applications of photoactive materials (e.g. nanocrystalline titanium dioxide). 

 
 
 

Our main topics:

  • Development of n-type semiconductor materials (e.g. titanium dioxide, tungsten oxide, iron oxide, etc. ) for oxidative photoelectrosynthetic reactions (e. g. production of bromine, persulfate, etc.) and oxidative degradation of organic pollutants using sunlight.
  • Development of p-type semiconductor materials for photoelectrochemical reduction reactions (hydrogen production, hydrogen peroxide production, etc.) using sunlight.
  • Synthesis of semiconductor materials for photocatalytic processes in aqueous and gaseous phase.
  • Photocatalytic processes in aqueous phase - degradation and mineralization of organic pollutants (pesticides, farmaceuticals, etc.)
  • Photocatalytic processes in gaseous phase – oxidative degradation and mineralization of gaseous pollutants (NOx, VOCs, etc. ) 
  • Semiconductor films fabricated by wet deposition techniques for gas sensing applications.
  • Construction and validation of various types of laboratory photoreactors for photocatalytic cleaning processes in aqueous and gaseous phase.
  • Development of photocatalytic air cleaners  - removal of VOCs and inactivation of microorganisms (bacteria, fungi).
