“…A widely used method is to replace a carbon atom with the doping atom in the graphene sheet. Currently, different doped-graphene sheets have been explored as toxic gas sensors, replacing a carbon atom by a dopant atom [ 55 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 ]. Around 30 elements of the periodic table have been explored for use as doping materials, with N being the most studied element dopant due to its similar atomic radii with C (see Table 4 ).…”

“…These structures are interesting because they show better reactivity toward the toxic gases than defective graphene [ 60 ]. Consequently, there have been various studies on the use of doped vacancy-defected graphene as toxic gases sensors [ 60 , 62 , 75 , 80 , 89 ]. Jia et al investigated the CO adsorption on Mn-doped vacancy-defected graphene using the PBE functional [ 62 ].…”

“…Recently, singleatom metal-modified graphene has been studied and is considered a promising catalyst. [18][19][20] The HDG could easily be generated by the chemical reaction. In the present study, we continue our previous calculations using HDG-M with N-dopants and with Htermination to investigate the adsorption properties between small gaseous molecules and HDG-M.…”
