Abstract

The metallic Cu nanoparticles have been successfully deposited on the heterogeneous TiO₂ surface by the borohydride reduction of copper nitrate in water/CH₃CN mixture under Ar atmosphere. The catalytic activity of the Cu–TiO₂ nanocomposite was evaluated by the application to a photocatalytic cancer cell-killing under UV–visible light irradiation. Based on the obtained results, a plausible mechanism was proposed.
