Welcome to the website of Triantafyllidis Research Group 


The Group of Prof. Konstantinos S. Triantafyllidis is part of the Laboratory of Chemical and Environmental Technology at the Department of Chemistry in Aristotle University of Thessaloniki (AUTH) in Greece. The group collaborates closely with the Laboratory of Environmental Fuels and Hydrocarbons at the Chemical Process & Energy Resources Institute (CPERI) of the Centre for Research and Technology-Hellas (CERTH).

Our group conducts fundamental and applied research in the fields of:

  • - Synthesis & Characterization of Materials
    Microporous zeolitic materials, ordered mesoporous materials, nano - metal oxides, layered materials, nanostructured silica or carbon based materials, hybrid organic - inorganic materials, polymer nanocomposites with advanced 1D, 2D and 3D inorganic nanostructures, bio-polymers and bio-composites.
  • - Heterogeneous Catalysis
    Catalytic cracking of hydrocarbons (FCC); De-NOx/De-SOx; cracking/upgrading of Fischer-Tropsch bio-waxes to gasoline and LPG; epoxidation of ethylene/propylene; dehydrogenation of alkanes; hydroisomerization of n-(bio)alkanes; biomass and lignin fast pyrolysis; bio-oil upgrading via (hydro)deoxygenation; hydrogenolysis of hemicellulose, cellulose and lignin to high value monomers/oligomers; hydrogenation, condensation, ketonization and esterification reactions of biomass derived platform chemicals; epoxidation of fatty acids and triglycerides, reactions for organic synthesis using "heterogenized" homogeneous catalysts (green chemistry).
  • - Thermochemical & (bio)catalytic processes for biomass valorization – Green Chemistry
    Hydrothermal (neat water, with/out dilute acids & solid catalysts) or organosolv (with mixtures of water/alcohols/organic acids) pretreatment of lignocellulosic biomass for selective separation and recovery of its components (cellulose, hemicellulose, lignin); utilization of (nano)cellulose as polymer additive; enzymatic or acid hydrolysis of biomass (cellulose) to produce sugars (glucose) for the production of bioethanol or sugar-derived furans, organic acids, etc.; utilization of lignin and derived phenolics, aromatics and cycloalkanes for the production of bio-resins, plastics and biofuels; fractionation/extraction of microalgae components to isolate lipids, proteins and utilization of residual carbohydrate biomass to produce aromatics by catalytic pyrolysis.
  • - Adsorption / separation processes (environmental applications)
    Synthesis/modification of porous materials such as zeolites, carbons, clays and layered double hydroxides (LDH), mesoporous materials, hybrid organic - inorganic materials, etc. for application in selective adsorption processes.


The group of Prof. Kostas Triantafyllidis is member of the COST Actions FP1306 - LIGNOVAL, CA17128 - LignoCOST and CA18220 - FUR4Sustain, all promoting the coordination of scientific and technological activities and capacity building at a European level, on biomass valorization towards fuels, chemicals and materials.
