Carbon Nanofibers for Environmental Remediation; A review

Carbon nanofibers (sometimes known as carbon nanofilaments or CNF) can be produced in a relative large scale by electrospinning of Polyacrylonitrile solution in dimethyl formaldehyde (DMF), stabilization and carbonization process. The porosity, pore volume and surface area of carbon nanofiber enhanced during the chemical or physical activation. This paper is a review of electrospinning method of CNF production and heat pretreatments and activations process to make activated carbon nanofiber (ACNF). Attention mostly is given to the possible applications of this nanostructures which owned unique porous as an effective absorbent for environmental pollutions treatment included air, water and waste water purification.
