Amongst 2D materials beyond graphene, MoS₂ and BN are considered potentially strong candidates for use in numerous ecological technologies such as treatment of polluted water and protection against bacterial infections. With these prospects in mind, nanocomposite was employed in this study as a remedy for problems related to environmental health. Nanocomposites of both host materials (MoS₂ and BN) were synthesized via applying liquid-phase exfoliation (LPE) strategy towards their bulk counterparts. In order to enhance its catalytic and antibacterial ability, host materials were doped with cobalt (Co) which serves as transition metal. This dopant was selected due to its band-less and charge facilitation characteristics. A hydrothermal approach was employed to prepare 4 and 8 wt.% concentrations of Co to synthesize doped samples. Several characterization techniques combined with Density Functional …
