Introduction:

The Surface Chemistry Group conjoines the traditions of the Hungarian Adsorption School with recent surface science achievements in materials science. Nanostructured carbon materials have been the centre of the group’s scientific activity, more specifically synthesis, morphology and surface properties of various types of carbon materials including activated carbon, carbon aerogels, as well as 2D carbon nanoparticles, like nanotubes and graphene derivatives. Beside working on carbon materials of tuned morphology and surface chemistry the group also works on the development of novel type single component and composite sorbents, like metal organic frameworks (MOFs), responsive soft matters and their hybride formed with various carbon materials. These materials are tested and optimized  for diverse applications, e.g., fuel cell electrode, catalyst, gas storage device, drug delivery and environmental applications.
