The evolution of spectra from pure TiO 2 films following annealing, Fig. 1a, reveals three bands located at 144, 395 and 638 cm −1 at 200 °C that are characteristic E g (Low-Frequency, LF), B 1g and E ...
Using numerical modeling, the joint research team from Russia, USA, and China has discovered new surface features of rutile TiO2, which is a promising photocatalyst "Our work has broadened the current ...
