INTRODUCTION

Graphene foams (GF) exhibit a high sorption capacity due to their high porosity and very low density, generally less than 0.01 g/cm3.

Due to their diverse chemical nature, they may exhibit specific sorption activity against various gases. These properties can be used

in the process of selective removal of individual gases from their mixtures. Graphene foams, due to their high sorption capacity, can

be applied as storage tanks for various gases. In future GF can be widely used in the removal of various types of gaseous and liquid

pollutants. Due to their high electrical conductivity GF can be used as an carrier for electrocatalysts in fuel cells, batteries and

supercapacitors as well as an excellent carrier for various types of metal and metal oxide nanoparticles used in catalytic chemical

processes. GF due to its high porosity is also an excellent heat insulator resistant to high temperatures and an aggressive chemical

environment.
