Abstract
Substituted polyoxometalate encapsulated into Y zeolite was synthesized with two ratios: H5PMo10W1Ti1O40.XH2O/Y (hereafter designated as SPY-1011, the numbers show the amount of Mo, W, Ti, respectively) and H5PMo1W10Ti1O40.XH2O/Y (hereafter designated as SPY-1101) was synthesized using the template synthesis method. The nanocomposite materials were characterized by XRD, FT-IR, UV-Vis, FESEM, and EDS techniques. The photocatalytic activity of systems was investigated within the photodegradation of methyl orange. The W, Mo, and Ti content of the catalyst was evaluated by the ICP method. The results showed that the photocatalyst performance depends on catalyst loading, pH effect, methyl orange concentration, type, and the number of substituted species. The chemical oxygen demand (COD) experiment indicated mineralisation of the methyl orange with 83% after 120 min irradiation. The absences of hydrazine during degradation confirmed by the amperometric experiment, in turn, showed methyl orange converted to simple inorganic materials. Photocatalytic degradation of methyl orange follows a pseudo-first-order kinetic.
