Abstract

Present work reports the newly synthesized resin polymethylene,bis-2-methoxy-1-napthaldehy-o-phenylenediimine (PMBMNOPhen) and then react with titanium dioxide and silicon dioxide to form encapsulated resin by metal oxide nanoparticles (PMBMNOPhenTiO(2)/SiO2) and resulted in the material is polymethylene,bis-2-methoxy-1-napthaldehy-o-phenylenediimine titanium-dioxide nanoparticles (PMBMNOPhenTiO(2)). The resin-encapsulated metal oxide nanoparticles were successfully identified morphology, crystal structure, and light absorption capacity of samples were characterized via scanning electron microscope (SEM), X-ray diffraction, energy dispersive (EDS) X-ray diffraction analysis (XRD) and ultraviolet-visible spectroscopy methods. Afterwards, the resin-encapsulated metaloxide nanoparticles are used for degradation of methylene orange (MO) dye. The photo-oxidation rate of the dye is dependent on the different parameters: initial dye concentration, effect of time, the effect of NaBH(4)and effect of dose of catalyst. The degradation of MO 60-80%% in real water samples with respect time of 30-60 minutes. These results confirm the prepared resin-encapsulated titanium dioxide nanoparticles (PMBMNOPhenTiO(2)/SiO2) displaying a great photocatalytic activity for the degradation of methylene orange dye under visible light irradiation effect of a catalyst in real water sample degradation. The synthesized catalyst (PMBMNOPhenTiO(2)/SiO2) was successfully applied in real dye water solution (colored water), collected from Jamshoro, Sindh (Pakistan). The resin-encapsulated metal oxide nanoparticles showed an excellent performance to reduce MO dye in contaminated water. These results approve that the resin-encapsulated titanium dioxide nanoparticles (PMBMNOPhenTiO(2)) display a great photocatalytic activity for the degradation of MO dye under visible light irradiation degradation. Photocatalytic degradation using resin-encapsulated (TiO2/SiO2) catalyst is effectively used for the textile dye (MO).
