ABOUT/BIOGRAPHY

Research Interests: nanoporous materials and membranes, adsorption and separation in the gaseous and liquid phase, photocatalysis.

Dr. G. E. Romanos is member of the Institute’s program “Nanochemistry and Nanomaterials” and principal member of the Lab “Membranes and Materials for Environmental Separations” at the Institute of Nanoscience and Nanotechnology of NCSR “Demokritos” (Group of 22 scientists). 

• Intense research activity in the domains of nanotechnology, environment and energy, with significant contribution in the development of advanced and novel materials, solvents (Ionic Liquids) and technologies for the capture of CO2. 
• Focus on the development of ultrathin layered, photocatalytic membranes (photocatalysis and processes), photoelectrochemical processes for the conversion of CO2 to fuels, processes for the capture of CO2 based on solid and liquid adsorbents. Large experience in functional nanocomposite materials (polymeric membranes with carbon nanotube and graphene based fillers for gas separation and desalination).
