Photocatalytic Activity Enhancement of Anatase TiO2 by Using TiO
(a) UPS spectra for PTiO and TT20 and (b) and (c) five fitted peaks (labeled by numbers I, II, III, IV, and V) of UPS spectra of PTiO and , respectively. The five peaks were fitted based on the expected contributions from the molecular orbitals that comprise the valence bonding states, respectively.
