Micro-mesoporous carbon materials

Physical and electrochemical properties of hydrogen, different solutions and hydrides in micro-mesoporous carbon materials

Group leader: Rasmus Palm, Institute of Chemistry, University of Tartu

Micro-/mesoporous carbon materials (MMCM) have important role in many energy storage technologies and devices (gas storage devices, supercapacitors, proton exchange membrane fuel cells etc.). The efficiency of these technologies depends on the thermodynamic and kinetic properties of materials used. It has been demonstrated that the properties (phase transition and decomposition temperatures, diffusion constant, catalytic activity etc.) of substances in nanoconfinement differ strongly form the properties of bulk material. We study the influence of MMCM properties on the physical andchemical properties of gases, solvents, solutions and hydrides (hydrogen, methane, water, ionic liquids, acetonitrile etc. organic solvent based solutions, sodium alanate, lithium borohydride etc.) adsorbed in the pores of MMCM at different experimental environments (pressure, temperature, applied potential etc.).
