Structure Regulation and Application of Bagasse-Based Porous Carbon Material Based on H2O2-Assisted Hydrothermal Treatment

“…After the O 1s peak separation, BH2-18 obtained the peaks of the CO bond and C–O bond at 531.5 and 533 eV. Moreover, BH5-18 and BH8-18 also obtained the peaks of OCO at 535.5 eV . XPS results showed that with the increase of the amount of H 2 O 2 added, the types of oxygen containing functional groups of the bagasse-based carbon materials increased (Figure g,h).…”

“…The information of elements and functional groups on the surface of carbon materials is shown in the XPS spectra. 43 XPS results showed that with the increase of the amount of H 2 O 2 added, the types of oxygen containing functional groups of the bagasse-based carbon materials increased (Figure 5g,h). Adding an appropriate amount of H 2 O 2 is helpful to improve the surface functional group structure of the carbon materials, but the addition of excessive H 2 O 2 might not be conducive to the improvement of the surface functional groups of the carbon materials (Figure 5e,f,h,i).…”

“…One spin−orbit doublet of Co 2p 3/2 can be divided into two deconvoluted peaks of Co 2+ (797.55 eV) and Co 3+ (795.76 eV). 32,33 The species. 34 Additionally, the two weak peaks located at 786.28 and 804.33 eV are marked as sat.…”

“…The Co 2p spectra of the YSS Co 3 O 4 @C nanoparticles (Figure e) consist of Co 2p 3/2 and Co 2p 1/2 . One spin–orbit doublet of Co 2p 3/2 can be divided into two deconvoluted peaks of Co 2+ (797.55 eV) and Co 3+ (795.76 eV). , The characteristic peaks of Co 2p 1/2 with binding energies of 780.79 and 782.50 eV are identified as the Co 3+ and Co 2+ species . Additionally, the two weak peaks located at 786.28 and 804.33 eV are marked as sat.…”

Mechanism of porosity development and defect engineering in chemically activated woven carbon fibres

“…Porous carbons, known as activated carbons, have been widely used in carbon dioxide (CO 2 ) separation and storage, 6 water treatment or dye degradation, 7,8 volatile organic compound (VOC) removal, 9 electronic devices, 10 and finally redox reactions. 11 Activated fibrous carbons or activated carbon cloths (ACCs) can address the typical fibre issues, including their poor contact efficiency with reagents followed by lower hydraulic permeability and limited specific surface area (SSA), restricting their prospective applications, especially in separation and adsorption. 12 This demonstrates the importance of generating porous structures.…”
