Cu-doped TiO2 nanopowders synthesized by sonochemical-assisted process narongdet wongpisutpaisan*, Naratip Vittayakorn,

Cu-doped TiO2 nanopowders were prepared by sonochemical-assisted process via a precursor solution of titanium isopropoxide, copper nitrate trihydrate and sodium hydroxide in the presence of polyvinyl alcohol in combination with calcinations process. The as-synthesized products were calcined at vario...

Their optical absorption properties were investigated and the results suggested that Cu dopant could significantly improve the optical absorption properties of TiO2.
