Graphene, an sp2 hybridized single sheet of carbon atoms organized in a honeycomb lattice, is a zero band gap semiconductor or semimetal. This emerging material has been the subject of recent intensive research due to the novelty of its structural, electronic, optical, mechanical, and magnetic properties. Due to these properties, graphene is a favorable material for the fabrication of electronic devices, transparent electrodes, spintronics devices, and a growing array of several other applications that explore the potential of this marvelous material. However, the lack of intrinsic band gap and nonmagnetic nature of graphene limit its practical applications in the widely expanding field of carbon-based devices. To take advantage of the hidden potential of this material, numerous techniques have been developed to tailor its electronic and magnetic properties. These methods include the mutual interaction between graphene layer and its substrate, doping with surface adatoms, substitutional doping, vacancy creation, and edges and strain manipulation. Herein, an overview of recently emerging innovative techniques adopted to tailor the electronic and magnetic properties of graphene is presented. The limitations, possible directions for future research and applications in diverse fields of these methods are also mentionedpublishersversionPeer reviewe

“…150 SNG prepared through the post-annealing process has been extensively studied. [151][152][153][154][155][156][157] We prepared macroporous SNG by annealing GO at 900 °C in Ar using melamine and BDS as the doping sources, and colloidal silica spheres as the hard template. 151 The S-doping level was 2.0 at.% with pure thiophene-S bonding; and the N-doping level was 4.5 at.% in the form of pyridinic, pyrrolic and graphitic-N. Wang et al indicated that the doping level in SNG was dependent on the reaction temperature; namely, the overall content of S and N dopants decreased with increasing temperature, with N content decreasing and S content increasing, indicating that an effective S-doping requires higher temperature.…”

To address the aggravating energy and environment issues, the cheap, highly active, and durable electrocatalysts as noble metal substitutes both at the anode and cathode are actively pursued. Among them, heteroatom-doped graphene-based materials show extraordinary electrocatalytic performance, some even close to or outperforming the state-of-the-art noble metals such as Pt and IrO 2 -based materials. This review provides a concise appraisal on graphene doping methods, the possible doping configurations and their unique electrochemical properties, including single-and double-doping with N, B, S, and P. In addition, heteroatom-doped graphene-based materials are reviewed as electrocatalysts for oxygen reduction (ORR), hydrogen evolution (HER), and oxygen evolution reactions (OER) in terms of their electrocatalytic mechanisms and performance. Significantly, three-dimensional (3D) heteroatom-doped graphene structures have been discussed, especially those that can be directly utilized as catalyst electrodes without extra binders and supports.

“…As a result, the maximum power density of 1159.34 mW m −2 obtained with PNCN catalyst in a MFC was higher than that of Pt/C catalyst (858.49 mW m −2 ). Additionally, carbon materials with multi-element doping, including nitrogen (N), boron (B), sulfur (S), or phosphorus (P) etc., have encouraged intensive research as promising metal-free ORR electrocatalysts in all kinds of fuel cells [19,[58][59][60][61][62]. However, this has not yet been completely evaluated in MFCs.…”

Microbial fuel cells (MFCs) are environmentally friendly technology capable of converting chemical energy stored in wastewaters directly into electrical energy by using microorganisms as biocatalysts. However, the overall low power density of the MFC and the high cost of its components are two major barriers for its commercialization. Among all the factors, the electrodes (cathode and anode) materials play the significant role in affecting the performance of MFCs. Recently, the performance of MFCs has been improved by using graphene-based electrodes that are more conductive and mechanically stable with larger surface area and higher electrocatalytic activity compared to the conventional carbon materials. This paper provides an overview of recent research progress in graphene-based materials as electrodes for MFCs, which will be the promising candidates for developing MFCs and other bioelectrochemical systems to achieve sustainable water/wastewater treatment and bioenergy production.
