The characteristics of TiO2 anatase from tulungagung sand as an antibacterial material

Abstract

TiO2 anatase is a material that has good photocatalytic properties. The synthesis of TiO2 anatase from Tulungagung natural sand used the leaching method. The synthesized samples were characterized by TGA, XRD, FTIR, BET, SEM, UV-DRS and tested for antibacterial effect. In this study, the TiO2 anatase phase was already formed and experiencing three stages of weight loss. It had stretching vibration of the OH group, had a bending mode of water Ti–OH, and Ti–O–Ti at wavenumbers 4000 to 400 cm−1. It also had a mesoporous size, was spherical with a grain size of 58 nm and had an energy gap of 3.42 eV. TiO2 anatase with a 600 µg/mL concentration could reduce Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa bacteria. Therefore, TiO2 anatase has the potential in an antibacterial agent.
