Synthesis and Application of TiO2-Phosphomolybdic acid nanocomposite

Tio2 doped with phosphomolybdic acid composites were synthesized by the blending method. the above prepared tio2-phosphomolybdic acid composites were characterized by uv-visible, ft-ir, xrd, sem and edax methods. photocatalytic degradation efficiency also studied. the uv-visible spectra showed a strong peak for the base tio2 and doped phosphomolybdic acid and the absorption spectra indicate a decrease in band-gap energy upon doping, and with slight increase in urbach energy. ft-ir structural features reveal the peak of tio2, phosphomolybdic acid and tio2-phosphomolybdic acid composite peaks. the xrd study proved that there was a slight decrease in the particle size in the composite materials. sem study also showed that a decrease in particle size and uniform distribution of dopant. heber multi lamp photo-reactor visible light irradiation of methylene blue (mb) dye was effectively degraded. the antibacterial effect against streptococcus mutans was examined using the disc diffusion method. this was shown to be effective against antibiotics and streptococcus mutans.
