Unraveling the antimicrobial activity of CuS functionalized titanates under visible LED light irradiation.

Titanate nanotubes (TNs) functionalized with CuS nanoparticles using the microwave-assisted hydrothermal method were characterized via XRD, Raman spectroscopy, UV-Vis spectrophotometry, and N physisorption. The as-synthesized CuS/TNs had anatase as the main crystalline phase and the band-gap energy was in the visible region, 2.9 eV.
