Abstract

Graphene foams (GF) exhibit a high sorption capacity due to their highporosity and very low density, generally less than 0.01 g/cm3. Due to theirdiverse chemical nature, they may exhibit specific sorption activity againstvarious gases. These properties can be used in the process of selectiveremoval of individual gases from their mixtures. Graphene foams, due to can be also used as an excellent carrier for electrocatalysts in various typesof fuel cells as well as an excellent carrier for various types of metal andmetal oxide nanoparticles used in catalytic chemical processes. GF due toits high porosity is also an excellent heat insulator resistant to hightemperatures and an aggressive chemical environment. The authors of thispresentation will present the synthesis process of various types of pure anddoped graphene foams and characterize their physicochemical properties.The starting material for these synthesis is graphene oxide and reducedgraphene oxide.their high sorption capacity, can be applied as storage tanks for variousgases. In future GF can be widely used in the removal of various types ofgaseous and liquid pollutants. Due to their high electrical conductivity GF
