“…These synthetic methods have produced graphene materials with monodopants [28,29] and codopants. [30,31] Importantly, experimentalists [32,33] and theoreticians [34] have joined forces to understand the mechanism of controlled growth with rationally designed doping features and to develop synthetic routes that are simple, economical, green, and scalable. [16,[35][36][37] These issues are critical to the reliable and large-scale production and application of graphene derivatives.…”

Chemically doped graphene materials are fascinating because these have different desirable attributes with possible synergy. The inert and gapless nature of graphene can be changed by adding a small number of heteroatoms to substitute carbon in the lattice. The doped material may display superior catalytic activities; durable, fast, and selective sensing; improved magnetic moments; photoresponses; and activity in chemical reactions. In the current review, recent advances are covered in chemically doped graphene. First, the different types of heteroatoms, their bonding configurations, and briefly their properties are discussed. This is followed by the description of various synthesis and analytical methods essential for assessing the characteristics of heterographene with specific focus on the selected graphene materials of different dopants (particularly, single dopants, including N, B, S, P, first three halogens, Ge, and Ga, and codopants, such as N/O), and more importantly, up‐to‐date applications enabled by the intentional doping. Finally, outlook and perspectives section review the existing challenges, future opportunities, and possible ways to improve the graphitic materials. The goal is to update and inspire the readers to establish novel doped graphene with valuable properties and for current and futuristic applications.

“…Turnover frequency (TOF) is used to quantify the catalytic activity of Ru@PDC and is defined as the number of [Fe(CN) 6 ] 3– molecules converted to [Fe(CN) 6 ] 4– with 1.0 mg of catalyst per s. Typically, 3.0 mmol of [Fe(CN) 6 ] 3– solution was completely reduced in the presence of Ru@PDC in 30 s, while Ru NPs and Ru/C exhibited lower catalytic activity within the same reaction time. We can simply calculate TOF values for a catalytic reaction using eq 7: 56 …”

The present study involves the synthesis, characterization, and catalytic application of ruthenium nanoparticles (Ru NPs) supported on plastic-derived carbons (PDCs) synthesized from plastic wastes (soft drink bottles) as an alternative carbon source. PDCs have been further activated with CO 2 and characterized by various analytical techniques. The catalytic activity of Ru@PDC for the reduction of potassium hexacyanoferrate(III), (K 3 [Fe(CN) 6 ]), and new fuchsin (NF) dye by NaBH 4 was performed under mild conditions. The PDCs had spherical morphology with an average size of 0.5 μm, and the Ru NP (5 ± 0.2 nm) loading (4.01 wt %) into the PDC provided high catalytic performance for catalytic reduction of ferrocyanate(III) and NF dye. This catalyst can be recycled more than six times with only a minor loss of its catalytic activity. In addition, the stability and reusability of the Ru@PDC catalyst are also discussed.

“…N/P codoped 3D graphene has been widely reported to have been synthesized by other synthesis protocols [82][83][84] but has been rarely developed by CVD. One of the first reports that dealt with the growth of N and P codoped porous graphene was made byMai and co-workers, who used methane and (NH 4 ) 3 PO 4 as the carbon and N and P sources, respectively.…”

Graphene doping principally commenced to compensate for its inert nature and create an appropriate bandgap. Doping of 3D graphene has emerged as a topic of interest because of attempts to combine its large available surface area-arising from its interconnected porous architecture-with superior catalytic, structural, chemical, and biocompatible characteristics that can be induced by doping. In light of the latest developments, this review provides an overview of the scalable chemical vapor deposition (CVD)-based growth of doped 3D graphene materials as well as their applications in various contexts, such as in devices used for energy generation and gas storage and biosensors. In particular, single-and multielement doping of 3D graphene by various dopants (such as nitrogen (N), boron (B), sulfur (S) and phosphorous (P)), the doping configurations of the resultant materials, an overview of recent developments in the field of CVD, and the influence of various parameters of CVD on graphene doping and 3D morphologies are focused in this paper. Finally, this report concludes the discussion by mentioning the existing challenges and future opportunities of these developing graphitic materials, intending to inspire the unveiling of more exciting functionalized 3D graphene morphologies and their potential properties, which can hopefully realize many possible applications.
