“…Foreign dopant atoms can alter the properties of graphene. Hence, doping has further opened the door to many graphene-based applications including electronics [38] and sensing [39] owing to the distinct nature of each dopant. [40,41] These impurity atoms display unique bonding configurations in the graphene lattice (see Figure 1i), endowing the graphene with distinctive properties.…”

“…For highly sensitive sensors of ammonia, Srivastava et al found that B-doped graphene exhibited speedy response (high sensitivity) to ammonia and immediate recovery. [39] The determination of hydrogen peroxide (H 2 O 2 ) has significance in both the industry and biological reactions. Zhang et al proposed a composite system (Co 3 O 4 decorated N-doped graphene) for fast, accurate, and reliable detection of H 2 O 2 .…”

“…The as‐grown sample was few‐layered according to Raman analysis, whereas the XPS result revealed two dominant bonding configurations (BC 3 (graphitic form) and BC 4 ) with a doping concentration up to 4.9 at%. [ 39 ] Incorporation of boron into the graphene framework has also been achieved via a two‐step CVD procedure. Pristine graphene is deposited by CVD, transferred to a target substrate, and then treated with a boron source solution.…”

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.

“…The results obtained indicated a new strategy to construct handy and quick gas sensing devices based on BFLGr. 51 2.1.4 Biosensors. Mannan et al synthesized GO using a modied Hummers method and successful boron doping (1.64-1.83%) was executed with boric acid as a precursor by hydrothermal reaction.…”
