Application of electrospun nanofibers for gaseous pollutants adsorption

Carbon dioxide is the most important greenhouse gas that is released in large quantities into the atmosphere. Excess carbon dioxide in the atmosphere is a problem for earth and increase the temperature and creates problems that affect human existence, such as severe tornadoes, storms, floods, droughts and acid rain. The largest source of outdoor CO2 is fossil fuel combustion, which are the main source of energy used to meet human energy demand now and in the near future. In recent years, nanofiber membranes have been highly regarded as pollutant adsorbents compared to conventional adsorbents, they have properties such as porous structure, high specific surface area, high penetration flux and selectivity, low pressure drop, high flexibility and targeted adsorption. So, electrospun nanofiber membranes have excellent potential for adsorption and separation of carbon dioxide from the air. In addition to the extremely high surface to volume ratio, modified electrospun nanofibers have different functional groups that improve their performance. Therefore, electrospun nanofiber membranes have excellent potential for adsorption and separation of carbon dioxide from the air
