Efficient electrocatalytic activity for oxygen reduction reaction by phosphorus-doped graphene using supercritical fluid processing

Boron doping positively enhances the catalytic activity of carbon materials for the removal of bisphenol A

“… 25 Balaji et al prepared a phosphorus-doped reduced graphene oxide (P-rGO) which delivered a better ORR performance (0.75 A mg −1 ) when compared with a commercial HiSPEC Pt/C (0.12 A mg −1 ) catalyst. 26 Kaipannan et al demonstrated that an activated carbon/ZnS (ACZS) nanocomposite electrode performed well as a supercapacitor and delivered a high specific capacitance of 241 F g −1 at 1 A g −1 current density. 27 Kang et al synthesized a porous boron-bearing carbon electrocatalyst doped with Fe and nitrogen (Fe-BNC), which showed a high surface area (1300 m 2 g −1 ) and favored a 4-electron reduction pathway for efficient ORR.…”

Advances in the synthesis of heteroatom-doped graphene-based materials and their application in sensors, adsorbents and catalysis

“…The resulting products exhibited hierarchical porous structures, which led to a high specific surface area of 541 m 2 g −1 . Balaji et al 97 reported for the first time the production of P-doped rGO (P-RGO) using triphenyl phosphine as the phosphorus source and GO in a supercritical fluid method. The ratio of phosphorus source and GO was varied to obtain optimum P-doping.…”

Phosphorus-Doped Graphene Electrocatalysts for Oxygen Reduction Reaction

“…Further theoretical and experimental works were conducted (some typical experimental works about P-graphene for ORR have been listed in Table 1 ) [ 75 , 76 , 77 , 78 , 79 ]. In Yang’s work, a phosphorus atom is believed to be the active site for ORR.…”
