Abstract
In this research, the g-C3N4@WO3 nanocomposites were synthesized from Na2WO4 and g-C3N4 via the hydrothermal method in a strong acid medium. The g-C3N4 content is 0, 0.5, 1, 3 and 5 wt%). The characterization of the g-C3N4@WO3 nanocomposites was measured by XRD, Raman, FT-IR, FESEM, and UV-vis spectra. The results show that g-C3N4@WO3 nanocomposites are hexagonal structural with an average crystal size of about 15.4 to 20.7 nm. The adsorption ability of the g-C3N4@WO3 nanocomposites was evaluated through the methylene blue dye absorption process. The optimal conditions of the MB adsorption process on the g-C3N4@WO3 nanocomposites were investigated. Moreover, equilibrium and kinetic modelling of the adsorption process also was studied and discussed.
