Abstract

Objectives: To synthesize a TiO2-phosphomolybdic acid composite by sonication method. The above prepared samples were characterized and study the application. Method: The above prepared composites were characterized by UV-Visible, FTIR, XRD, EDAX and SEM studies. Also, the applications studies such as, photocatalytic activities, antimicrobial activities and electrical conductivities. Findings: The UV-Visible and FTIR shows that there is a strong interaction between TiO2 and the dopant, phosphomolybdic acid. XRD and SEM showed a decrease in particle size and uniform distribution of dopant, phosphomolybdic acid into the TiO2 matrix. The composite exhibited excellent photo-catalytic activity, with a degradation of MB at a rate of 99.58% with in 180min. The composites also had good antimicrobial activity with an inhibition rate 99%. The composites had good electrical conductivity with a conductivity of 100s/cm. Novelty: The light sensitizer functionality of TiO2 and heterogeneous catalysis of phosphomolybdic acid, PMA have been combined in the composites.

Keywords: Composite; TiO2 Phosphomolybdic Acid; Photocatalytic Activity; Streptococcus pyogenes; Dielectric Constant
