Abstract
Microstructural change and MB removal tests were studied of MoO3 as a function of heat treatment. Synthesized materials were mill and stabilize it structure for MB removal by milling and heating process. It was found that the optimized material can be reused cyclically, obtaining always 100% of the MB removal. Around 90% of MB removal was reached in ∼30 min. The removal process has not influence by UV-Vis illumination, it works by adsorption. Morphology and microstructure were studied by electron microscopy techniques and XRD techniques. By infrared spectroscopy was characterize the material for recycling process on MB removal. XRD patterns were refine by Rietveld method to determine lattice parameters, percentage of phases, crystal sizes and anionic vacancies concentration. The thermal stability of materials was study by thermogravimetric analysis and differential scanning calorimetry. Optimized material could be reused to MB removal.
