Copper doped titanium dioxide (TiO2) nanoparticles for enhanced photocatalytic activity under visible light irradiation

Titanium dioxide (TiO2) is best known for its inexpensiveness and highly available as a photocatalyst. However, due to its wide-bandgap of 3.2 eV and the fast recombination of electron-hole pair, they have contributed to the inability to use the sunlight sufficiently as well as hindering for any rea...
