  • TiO2-TG analyses -OH groups

    Dane Badawcze
    open access

    TG analyses of TiO2 were performed under nitrogen flow to monitor desorption of hydroxyl groups. Physisorbed weak-bonded hydroxyl groups were desorbed totally at around 120oC, whereas chemisorbed ones at around 500oC. The mass loss at these temperatures was used as concentration of hydroxyl groups on TiO2 surface. The amount of analysed TiO2 was 10...

  • TG-hydroxyl groups in TiO2-P25

    Dane Badawcze
    open access

    TG analyses were performed for powdered TiO2 - commercial P25 sample, which was heat-treated from room temperature to 500 C in the nitrogen atmosphere. Mass loss at lower temperature such as 120 C was related to the physisorbed water, and that one occurring at 500 C to the chemisorbed hydroxyl groups.
