Department of Chemistry of Solids in IIC
Scope
Researchers are mostly focused on materials chemistry including development for the practice. The research results are hence not only papers, but also patents and design of novel technologies for practical applications. They are based on own research. The main current topics are:

Equipment
Synthesis laboratories are conventionally equipped for laboratory syntheses, autoclaves (300°C, 20 MPa), tube ovens, high-performance ultrasound generators. It is possible to use a pilot plant and work on transfer of technologies to larger scales for practical applications. Laboratories are equipped for preparation of thin films using sol-gel procedures.
Reaction kinetics with solid catalysts is studied with help of quadrupole mass spectrometer JEOL JMS- Q1000GC, gas chromatograph AGILENT 6890N. Solids are characterised by surface area measurement (Coulter SA 3100), particle size analyser Malvern-ZetaSizer, UV-VIS spectrometer Lambda 35 with integration sphere, colorimeter for solids Hunterlab ColorQuest and fluorescence spectrometer AVANTES.
Catalytic activity of newly prepared chemical materials is studied in photoreactors in liquid/solid and gas/solid systems (more details on reactors).
