Effects of Doped N, B, P, and S Atoms on Graphene toward Oxygen Evolution Reactions

Abstract: Molecular oxygen and hydrogen can be obtained from the water-splitting process through the electrolysis technique. However, harnessing energy is very challenging in this way due to the involvement of the 4e– reaction pathway, which is associated with a substantial amount of reaction barrier. After the report of the first N-doped graphene acting as an oxygen reduction reaction catalyst, the scientific community set out on exploring more reliable doping materials, better material engineering techniques, and deve… Show more

“…Even more, it was found that the MOR is considerably improved on the GNH@PtNP-modified electrode (Figure C). At first, it is supposed that MOR forward current should be more significant on the GSH@PtNP-modified electrode due to the high affinity between thiol groups and PtNPs. , Theoretically, Mallik et al have also shown a much more efficient catalytic activity on S-doped compared to N-doped graphene . Surprisingly, the forward current obtained on the GNH@PtNP-modified electrode in methanol solution is 20 times higher than that on the GSH@PtNP-modified electrode.…”

“…The anchoring sites based on sulfur- or nitrogen-containing moieties can be introduced via chemical doping or functionalization of graphene flakes. In the former approach, the heteroatoms (S, N, O, P) are embedded in carbonaceous planes. The replacement of carbon with doping atoms in the backbone could tune electrical behavior , or make the support become a metal-free catalyst in some cases. It was recently reported that the surface corrugations such as nanoscale ripples might play a role in the catalytic activity of graphene .…”

“…56,57 In our previous work, we implemented the well-tempered metadynamics, 58 a fastgrowing method that provided great details about the reaction mechanism of a dynamically evolving system in the condensed phase. 59,60 However, quantitatively finding the overpotential was not feasible following the fast growth method. Also, implementing a constant potential model has become a prerequisite for the unerring calculation of the overpotential.…”

“…Heteroatoms like N, S, B, P, and Si, entrenched in carbon sheets, modify the electronic structure of the carbon frameworks by tailoring the Fermi energy levels and tuning the local electronegativity. Heteroatom containing extended π-conjugated organic polymer materials have been already established as an efficient candidate towards electro/photo/ photo-electro catalytic activity in water oxidation (Xu et al, 2016;Xie et al, 2017;Priyadarsini and Mallik, 2021). Recently, S and N embodied porous organic frameworks have been explored in detail towards catalytic activity.…”
