Synthesis of 2D MoO3−x/N-doped-carbon nanocomposites via in situ carbonization of layered (NH4)Mo3O9–(NH4)2Mo4O13-organic hybrid nanomaterials for exceptionally efficient adsorption and separation of organic dyes

“…The electrostatic interaction can explain this observable fact. 12,[18][19][20]46,66,67 The low adsorption capacity at lower pH values is primarily due to the electrostatic repulsion between protonated adsorption sites on the MoO 3−x /N-C nanocomposites and protonated dimethylamine group on MB. The electrostatic repulsion weakened on the MoO 3−x /N-C nanocomposites with MB molecules, increasing pH values and decreasing consequent protonation.…”

“…4,10,11 Nitrogen-doped-carbon adsorbents have been reported for their enhanced adsorption capacity as well as selectivity because the N-doped sites act as Lewis bases to enhance the primary characteristics of porous carbons. 6,12 Recently, several transition metal oxide (TMO)-based nano/ microstructures were reported to exhibit improved removal capability for organic dyes in water by the adsorption mechanism, with enhanced reusability, e.g., nickel oxide, 13 zinc oxide, 14 copper oxide, 15 iron oxide, 16 tungsten oxide, 17 and molybdenum trioxide (α-MoO 3 ). [18][19][20][21][22][23][24][25][26][27][28] Compared to the activated carbon, TMO nanostructures exhibited comparable adsorption capacities and induced selectivity based on surface functionalization.…”

A review on sustainable production of graphene and related life cycle assessment

“…The dried okara was carbonized at 800 • C in N 2 atmosphere and a layered, oxidised material was obtained (9.43 at.% O, 2.17 at.% N). Soybean flour has been also used as starting material, by treating a mixture with glucose at 180 • C for 8 h in an autoclave [128]. The resulting product was characterized as few-µm carbon spheroids composed of graphitic layers that displayed the typical graphite/graphene XRD peaks.…”
