“…Various biomasses used for the production of carbon nanofibers include lignocellulose materials [63][64][65][66][67][68][69] such as cellulose, hemicellulose [70], lignin [71,72], bamboo [73], crab shell [74], natural fungus [75,76], sawdust [9], seafood chitin [77], coconut shell charcoal [78] etc. On other hand, carbon nanofiber also can be prepared from polymers, such as polyacrylonitrile (PAN) [79,80], poly(vinyl alcohol) [81], vanillin polymer [82] and poly-(vinyl pyrrolidone) [83].…”

“…The results revealed that FCL exhibited capacity values of 1.3 mmol/g, with full regeneration of the carbon material at the same condition without any additional energy. More recently, Zainab et al analyzed the efficient CO 2 capture by polyacrylonitrile-poly(vinyl pyrrolidone) (PAN/PVP) carbon nanofibers obtained via electrospinning with subsequent intensive washing and carbonization treatment [83]. The authors suggested that the PAN/PVP carbon nanofibers showed a high selectivity with a CO 2 adsorption capacity of 3.11 mmol/g.…”

In recent years, ecological issues have led to the search for new green materials from biomass as precursors for producing carbon materials (CNFs). Such green materials are more attractive than traditional petroleum-based materials, which are environmentally harmful and non-biodegradable. Biomass could be ideal precursors for nanofibers since they stem from renewable sources and are low-cost. Recently, many authors have focused intensively on nanofibers’ production from biomass using microwave-assisted pyrolysis, hydrothermal treatment, ultrasonication method, but only a few on electrospinning methods. Moreover, still few studies deal with the production of electrospun carbon nanofibers from biomass. This review focuses on the new developments and trends of electrospun carbon nanofibers from biomass and aims to fill this research gap. The review is focusing on recollecting the most recent investigations about the preparation of carbon nanofiber from biomass and biopolymers as precursors using electrospinning as the manufacturing method, and the most important applications, such as energy storage that include fuel cells, electrochemical batteries and supercapacitors, as well as wastewater treatment, CO2 capture, and medicine.

“…In a very recent study, Zainab et al mixed PVP and PAN solution together for electrospinning to form PNFs, which were then dried in a vacuum and hydrolyzed to obtain porous CNFs after selectively removing the PVP precursor. 126 This created material has good selectivity for CO 2 and could be useful for the further fabrication of 3D CNF-based functional nanomaterials for the capture of CO 2 .…”

“…Therefore, the ACNF composites presented comparable CO 2 and CH 4 adsorption capacities. Zainab et al prepared porous CNFs to develop efficient adsorbents for CO 2 capture and reported that the prepared CNFs presented CO 2 adsorption performance of 3.11 mmol/g [45]. In a different work, Abbasi et al examined the amine-bearing nanofibrous adsorbent for the CO 2 adsorption at ambient conditions [46].…”

PAN-based activated carbon nanofiber/metal oxide composites for CO2 and CH4 adsorption: influence of metal oxide

2021

In the present study, we successfully prepared two different electrospun polyacrylonitrile (PAN) based-activated carbon nanofiber (ACNF) composites by incorporation of well-distributed Fe 2 O 3 and Co 3 O 4 nanoparticles (NPs). The influence of metal oxide on the structural, morphological, and textural properties of final composites was thoroughly investigated. The results showed that the morphological and textural properties could be easily tuned by changing the metal oxide NPs. Even though, the ACNF composites were not chemically activated by any activation agent, they presented relatively high surface areas (S BET ) calculated by Brunauer–Emmett–Teller (BET) equation as 212.21 and 185.12 m 2 /g for ACNF/Fe 2 O 3 and ACNF/Co 3 O 4 composites, respectively. Furthermore, the ACNF composites were utilized as candidate adsorbents for CO 2 and CH 4 adsorption. The ACNF/Fe 2 O 3 and ACNF/Co 3 O 4 composites resulted the highest CO 2 adsorption capacities of 1.502 and 2.166 mmol/g at 0 °C, respectively, whereas the highest CH 4 adsorption capacities were obtained to be 0.516 and 0.661 mmol/g at 0 °C by ACNF/Fe 2 O 3 and ACNF/Co 3 O 4 composites, respectively. The isosteric heats calculated lower than 80 kJ/mol showed that the adsorption processes of CO 2 and CH 4 were mainly dominated by physical adsorption for both ACNF composites. Our findings indicated that ACNF-metal oxide composites are useful materials for designing of CO 2 and CH 4 adsorption systems.
