Visible-light photocatalysis with phosphorus-doped titanium(IV) oxide particles prepared using a phosphide compound

► Phosphorus-doped TiO2 was prepared by doping TiO2 with phosphorus having negative charges. ► The P-doped TiO2 nanoparticles exhibited a pale yellow color. ► The action spectra for acetaldehyde decomposition revealed visible light activity of P-TiO2. ► The photocatalytic activity of P-TiO2 depended on calcination temperature.
