“…The isotherms of YRFC and SRFC exhibited representative type‐IV features (Fig. a), which are well accordance with the IUPAC classification . Two types of carbon spheres display obvious hysteresis loops in the relative pressure range of 0.45–0.9 P / P 0 , implying that the presence of mesopores structures.…”

In this article, the yolk–shell structure of resin‐based carbon spheres (YRFC) and the solid structure of resin‐based carbon spheres (SRFC) were prepared by condensation polymerization, and then novel spherical composites of poly(3,4‐propylenedioxythiophene)/YRFC (PProDOT/YRFC) and PProDOT/SRFC were obtained by in situ chemical oxidative polymerization. The prepared composites were characterized by Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible absorption spectra (UV–vis), Raman, X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET), X‐ray photoelectron spectrometer (XPS), scanning electron microscope (SEM), and transmission electron microscopy (TEM). Electrochemical behavior of the composites were investigated with reference to their suitability as electrode materials in electrochemical capacitors (ECs), which were accomplished by a combination of cyclic voltammetry and galvanostatic charge/discharge cycles. The resultant PProDOT/YRFC composite showed ideal charge storage capacity with a specific capacitance of 327.5 F g−1 at the current density of 1 A g−1, which is much higher than that of the materials of PProDOT/SRFC (298.1 F g−1) and PProDOT (180.9 F g−1). Furthermore, long cycle life was achieved with the optimized PProDOT/YRFC and the capacitance retention is 87.3% after 10,000 charge/discharge processes, which was attributed to its uniformly dispersible fluffy structure.

“…LEP is a widely used, IUPAC recommended, non-hazardous (no mercury) method to assess the porosity of ceramics, food products and nonwoven fibrous filter media beds [58–61]. The porosity (%) and median pore diameter for all MWCNT scaffolds (MWCNT:BP mass ratios between 1:0.5, to 1:4) is presented in Figure 5C and Table 4.…”

We report a simple method to fabricate macroscopic, 3-D, free standing, all-carbon scaffolds (porous structures) using multiwalled carbon nanotubes (MWCNTs) as the starting materials. The scaffolds prepared by radical initiated thermal crosslinking, and annealing of MWCNTs possess macroscale interconnected pores, robust structural integrity, stability, and conductivity. The porosity of the three-dimensional structure can be controlled by varying the amount of radical initiator, thereby allowing the design of porous scaffolds tailored towards specific potential applications. This method also allows the fabrication of 3-D scaffolds using other carbon nanomaterials such as single-walled carbon nanotubes, fullerenes, and graphene indicating that it could be used as a versatile method for 3-D assembly of carbon nanostructures with pi bond networks.

“…The low-pressure nitrogen adsorption process (LPNA) was carried out at the temperature of 77 K. The multilayer adsorption theory Brunauer-Emmett-Teller (BET) 25 was used in the relative pressure range p/p 0 0.05-0.30. The analyses of macrostructure of NaHCO 3 used mercury porosimetry (MIP) 26 . The analysis were made with AutoPore IV 9500 (Micromeritics Instrument Corporation, USA).…”

The article presents the effects of mechanical and thermal modification on the surface area of sodium bicarbonate and its ability to remove SO 2 and HCl from exhaust fumes.The mechanical modification consisted of grinding in an impact mill. The thermal modification consisted of heating in the temperature range from 373 K to 673 K. The applied modifications caused a change in the grain structure of sodium bicarbonate and parameters such as specific surface area and the pore size. The parameters were determined by low-pressure nitrogen adsorption (LPNA) and mercury porosimetry (MIP) methods. The largest development of the active surface, which was up to 6 m 2 g -1 (LPNA), was achieved after crushing and heating in the temperature range of 423-523 K.The efficiency of a simultaneous purification of fumes from SO 2 i HCl on a continuous-combustion installation with a circular fluidised bed CFB was determined. The samples were fed into the installation in three different molar ratios 2Na/S (0.5; 1.0; 2.1) in a gas jet of 573 K. It was shown that the removal of SO 2 and HCl took place simultaneously and mainly on the grain surface. The average efficiency of SO 2 purification was between 17 % and 89 %, and it depended on the comminution degree and the amount of the sorbent. The efficiency of HCl removal was between 54 and 78 %.
