The partial reduction of TiO 2 was investigated by hydrogen plasma treatment and it was performed to examine the oxygen absorption property of partially reduced TiO 2 (TiO 2-x). In this experiment, TiO 2-x was analyzed by X-ray diffraction (XRD) and oxygen absorption of partially reduced TiO 2 was measured by gas chromatography (GC). Consequently, it was shown that hydrogen plasma treatment can partially reduce TiO 2 by plasma effects and TiO 2-x can adsorb oxygen. The H 2O formation and the oxygen absorption were found to be dependent on the heating temperature. The oxygen absorption property was attributed to the formation of Ti 2O 3.
