“…As it can be observed in Table 1, the obtained PSD and S S are 8.6 ± 3.5 nm and 60 m 2 g −1 , respectively. Recently, we reported the values of both mesopore size and mesopore surface area obtained by nitrogen adsorption isotherms for the same monolithic carbon sample (10 nm and 57 m 2 g −1 , respectively) (Bruno et al, 2010), and those values correlate well with our results obtained by FIB-nt method. However, the PCM sample can reach a BET surface area of about 700 m 2 g −1 .…”

“…Such measurements In this contribution, FIB-nt will be employed not only to obtain a visual 3D morphology representation of disordered nanoporous carbon, but also to characterize in detail their structural parameters such as: specific surface area, pore size distribution, total porosity and connectivity of pores. The results will be compared to measurements done with nitrogen sorption isotherm method, in which the specific surface area and the pore size distribution of the same sample were determined (Bruno et al, 2010). Given that the porous structure of synthetic disordered porous carbons, like carbon aerogels (Moreno-Castilla & Maldonado-Hódar, 2005), can be controlled from synthetic conditions (Bruno et al, 2010), the studies of the porosity and connectivity of the pores via characterizations using FIB-nt measurement would allow the choice of the best carbon material for technological applications, such as electric double layer supercapacitors, fuel cell electrodes, lithium batteries and catalyst support.…”

“…In general, the M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 4 carbon monoliths are isotropic materials; however, some monoliths are anisotropic and show carbon walls and channels, both aligned along a specific direction of the monolith [21]. The main drawback of the carbon monoliths is their low density, typically lower than 0.5-0.6 g cm -3 [2,[20][21][22][23][24][25][26][27][28][29][30][31][32]. Consequently, their volumetric capacitance is usually low, below 100 F cm -3 in aqueous electrolytes and below 50 F cm -3 in organic ones.…”
