Igh temperature (273 K) was utilized to probe the microporosity of HPCs. The adsorbed quantity (inset in Figure 2a) for HPC8 have close pore-structure parameters for HPCs (Table 2) recommend that even though HPCs BET particular HPC6 areas, the entire relative pressure area, indicating a can also be higher than that ofsurface inside the micropore surface area determined by the CO2 probe for HPC8 is much larger HPC8. far more developed microporosity forthan that of HPC6.Figure 2.

Such a outcome can coincide well with the HR-TEM observation (Figure 1e,g). The calculated d002 for HPCs is about 0.418 nm. The greater d002 worth compared with that of graphite is most likely because of the heteroatom doping, which expands the interlayer distance among adjacent carbon layers. Two distinct peaks within the Raman spectra for HPCs (Figure 3b) at 1351 and 1589 cm-1 are assigned towards the D and G bands for carbon supplies, respectively. The D band is assigned for the disorder-induced mode associated with structural defects and imperfections while the G band is assigned for the first-order scattering in the E2g mode from the sp2 carbon domains [26]. The intensity ratio IG /ID is made use of as a measure in the graphitization degree for carbon samples. Each HPCs possess an IG /ID worth larger than 1, 1.11 for HPC6 and 1.09 for HPC8, indicating an excellent graphitization degree for HPCs. The XPS analyses show that phosphorus and nitrogen are doped in HPCs (Figure 3c). The N 1s spectrum may be deconvolved into three peaks at 398.1, 400.5 and 403.three eV, which may very well be assigned to pyridinic (N1), pyrrolic (N2) and pyridine-N-oxide (N3) nitrogen species, Fmoc-Gly-Gly-OH supplier respectively [27]. The P 2p spectrum could be deconvolved into 3 peaks at 131.two, 132.eight and 134.3 eV, corresponding to P-C bonding (P1), pyrophosphate ([P2 O7 ]4- , P2) and metaphosphate ([PO3 ]- , P3) species, respectively [22]. The contents of N and P (Table 1) in HPCs suggests that nitrogen would escape below a high-temperature remedy although P prefers to remain below a higher temperature.Nanomaterials 2021, 11, 2838 Nanomaterials 2021, 11, x FOR PEER REVIEW7 7 of12 ofFigure three.
