KOH-activated graphite nanofibers as CO2adsorbents

Abstract: Porous carbons have attracted much attention for their novel application in gas storage. In this study, porous graphite nano-fiber (PGNFs)-based graphite nano fibers (GNFs) were prepared by KOH activation to act as adsorbents. The GNFs were activated with KOH by changing the GNF/KOH weight ratio from 0 through 5 at 900°C. The effects of the GNF/ KOH weight ratios on the pore structures were also addressed with scanning electron microscope and N 2 adsorption/desorption measurements. We found that the activated … Show more

“…However, as the awareness of the risk of hydrocarbon vapor from automobiles increases, the regulation is becoming more and more intense, and the needs for ACs with superior hydrocarbon vapor adsorption capability is increasing . Traditionally, it is known that the adsorption capacity of ACs greatly depends on the pore characteristics. , However, there is not much research on the correlation between hydrocarbon vapor generated in automobiles and pore characteristics of ACs …”

“…13 Traditionally, it is known that the adsorption capacity of ACs greatly depends on the pore characteristics. 14,15 However, there is not much research on the correlation between hydrocarbon vapor generated in automobiles and pore characteristics of ACs. 16 The adsorption capacity evaluation for hydrocarbon vapor of ACs is generally measured by calculating the weight change caused by the adsorption and desorption process according to ASTM-D5228.…”

“…On the other hand, the interaction between microorganism and carbon materials is still unknown, which is the main factor limiting further improvement of the performance of the MES process. For example, insufficient information about microbecarbon interactions is delaying the advance of the process significantly when the input potential is <−410 mV vs standard hydrogen electrode (SHE), which is the theoretical minimum potential for hydrogen production [9].Carbon has been recognized as the best material for fuel cell applications owing to its good electrical conductivity, its potential for the impregnation of catalysts, and its cost effectiveness [10,11]. For the same reasons, a range of morphologies of carbon materials have been utilized as anode and cathode electrodes in BES in the form of carbon paper, cloth, graphite rod, and felt in BES systems [12].…”
