Fabrication of novel g-C3N4 based MoS2 and Bi2O3 nanorods embedded ternary nanocomposites for superior photocatalytic performance and destruction of bacteria
High efficient g-C3N4 based MoS2/Bi2O3 nanorods embedded novel nanocomposites (g-C3N4/MoS2/Bi2O3) was effectively fabricated by the hydrothermal-calcination way. The chemical composition, deep morphology, structure, optical absorption, and photocatalytic belongings of the as-obtained g-C3N4/MoS2/Bi2O3 photocatalysts were considered and well-discussed. HR-TEM outcomes were obviously proposed that the MoS2/Bi2O3 nanorods could be well-composed in the g-C3N4 superficial without clear aggregation. The superior photocatalytic efficacy of g-C3N4/MoS2/Bi2O3 nanocomposite under visible-light revelation has been evaluated by methylene blue (MB) dye photo-degradation. In the 90 min of visible-light exposure time, the decolourization proficiency was attained closely 98.5 % and the removal rate of MB dye decomposition was reached in g-C3N4/MoS2/Bi2O3 photocatalyst, which was 1.4 and 3.6 folds larger than that of as-obtained g-C3N4 and g-C3N4-MoS2 photocatalysts singly. The greater photocatalytic action of g-C3N4/MoS2/Bi2O3 nanocomposites might inhibit the recombination of active migration/separation for photo-excited charges (e-/h+), lesser bandgap, and its durable fascination of visible-light. Likewise, as-prepared nanocomposite has exposed better antibacterial assets against both E.coli and S.aureus bacteria. Also, these novel g-C3N4/MoS2/Bi2O3 nanocomposites keep great eventual for visible-light exposed destruction of organic tints as of industrial wastewater.
