Nanoscale carbon material porosity effect on gas adsorption

Effectiveness Research on a Wavy Lamellar Plate-Type Biofilter With a Capillary System for the Humidification of the Packing Material Applying Introinduced Microorganisms

“…In this case, the porosity of the packing material and capillary play a leading role. It has been established that a higher porosity of the material causes better absorption of pollutants from the contaminated air (Beyaz et al 2010). Herewith, a higher porosity of the material makes the capillary humidification of the packing material more effective.…”

Biological Breakdown Efficiency Research of Wavy Lamellar Structure Air Purification Biofilter with a Capillary Load Moistening System

“…One of these properties is the bioload's porosity and capillarity. It has been determined that the higher the material's porosity, the faster is the rate of absorption from polluted air [30]. Moreover, a higher porosity of the material means that the bioload's capillary moistening is more effective.…”

On the feasibility of developing hydrogen storages capable of adsorption hydrogen both in its molecular and atomic states

“…The ultimate amount of adsorbed hydrogen is within 1.5wt.%. Table 2 given below systematize some of the most typical data on adsorption of hydrogen by nanotubes, nanofibers, and activated carbon [23]. The analysis of the given results hardly allows for establishing any pattern that would correlate the High surface area i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 7 ( 2 0 1 2 ) 1 8 0 6 1 e1 8 0 7 3 value of specific pore surface (SBET) with the amount of adsorbed hydrogen (wt.…”

“…The Table shows that the reduction of specific pore surface causes no decrease in the amount of absorbed hydrogen. It is explained by the fact that depending on the methods of preparation of activated graphite different amount of narrow cylindrical pores is formed, which is not taken into account for the calculation of specific surface [23].…”
