    Mesoporous carbon spheres (CSs-H) were hydrothermally synthesised using sugar as carbon source. The as-synthesized CSs-H was microporous but after thermal treatment at 900 °C for 4 h it became mesoporous (surface area of ...
  • Yokwana, Kholiswa; Kuvarega, Alex T.; Mhlanga, Sabelo D.; Nxumalo, Edward N. (Elsevier, 2018)
    This work reports the mechanistic models responsible for the adsorptive removal of Congo red (CR) dye molecules by nitrogen-doped graphene oxide nanosheets (NGO) prepared via a one-pot modified Hummer's method using ...
  • Zikalala, S.A. (Elsevier, 2018)
    This work systematically evaluates the effect of synthetic routes on the physicochemical and optical properties of nitrogen-doped titania (NTiO2) nanohybrids supported on oxidized carbon nanotubes (oxCNTs). A series of ...
