Modified carbon materials
Research Fields:
Chemistry
Previous and Current Research
Scientific interest is focused on the development of novel synthetic approaches for the surface modification of advanced granular and fibrous carbon materials and their application as:
- acid-base catalysts as an alternative to liquid acids for dehydration, esterification, alkylation, isomerization etc.
- ion-exchange materials for water preparation - softening and desalination
- catalyst carriers for various acid-base and red-ox reactions
- sorbents for extraction of heavy metals from wastewaters in different industries
Methodological and Technical Expertise
- Synthesis of carbon materials with grafted CFx-, SO3H- and NAlk2-groups
- All experimental approaches for characterization of modified carbon materials by physical and physicochemical methods
- All experimental approaches for characterization of acid-base and red-ox catalysts
- Synthesis of high purity inorganic glasses
- Quantum-chemical modeling of carbon materials
