Hydrothermal co-doping of boron and phosphorus into porous carbons prepared from petroleum coke to improve oxidation resistance

Preparation of boron-doped hydrothermal carbon from glucose for carbon paste electrode

“…Decrease of these two parameters suggests structural ordering caused by the presence of substitutionally incorporated boron [21,22,43,44]. Namely, I D /I G value is directly associated to the degree of carbon structure disorder [45][46][47] and normally decreases on (i) decreasing the number of defects present in the material and/or (ii) increasing the graphite crystal size [48]. Additionally, the decrease of the G peak bandwidth indicates carbon structure graphitization increase [43].…”

“…Additionally, Wu et al [47] connect increase in degree of carbon structure disorder as a result of the introduction of certain functional groups (e.g.\COOH and\OH). oxygen groups which decompose during heating by releasing CO and CO 2 .…”

“…Increment of QCO 2 and particularly QCO for sample CHTCB 1 indicate that nominal boron content above 1 wt.% could induce catalytic effect on surface oxygen group formation especially CO releasing oxygen groups. Additionally, Raman spectroscopy results suggested disturbance of structural parameters for sample CHTCB 1 which could be induced by higher presence of surface oxides[47]. Our previous results[23,24] related to subtitutional incorporation of boron into glassy carbon, showed that presence of B resulted in weakening of C-C bond and strengthening of C-O bonds.This was reflected over catalytic effect on the surface C-O complexes formation.…”

One‐pot synthesis of high N‐doped porous carbons derived from a N‐rich oil palm biomass residue in low temperature for CO 2 capture

“…Moreover, for OAC-500-2.5, the calculated selectivity was 15.7 at 1 bar and mixture (CO 2 : N 2 = 15:85), which was similar or higher to those of Ndoped adsorbents published recently. 37,38 Because of the difference between N 2 and CO 2 , CO 2 molecules could form hydrogen bonds and react with prepared adsorbent, but there was no strong interaction between N 2 and adsorbents. 39 This resulted in a high CO 2 adsorption and low N 2 adsorption.…”

Nitrogen and sulfur co-doped nanoporous carbon material derived from p-nitrobenzenamine within several minutes and the supercapacitor application

“…Generally, there are two major approaches to accomplish the doping of heteroatom. One is by pyrolyzing heteroatom-containing precursors directly [6,7], and the other is by post-treating carbons with dopants [8,9]. The doping candidates have been reported including nitrogen, sulfur, boron and phosphorus etc [10].…”
