Ageing of Photocatalytic Materials: Investigation, Assessment and Possible Solving
The stability of composite materials (TiO2-film deposited on a kaolinite and montmorillonite matrix) in time was investigated. The obtained results showed that the adsorption activity (capacity and specific area) decreased in comparison with the results of 2011. It was found that the samples in whic...

| description | The stability of composite materials (TiO2-film deposited on a kaolinite and montmorillonite matrix) in time was investigated. The obtained results showed that the adsorption activity (capacity and specific area) decreased in comparison with the results of 2011. It was found that the samples in which the content of titanium dioxide is not more than 100-120 mg/g, characterized by the highest stability. As regards the influence of UV-radiation, the results demonstrate that the sensitivity to UV radiation for kaolinite matrix materials increases as the estimated content of TiO2 up to 100 mg/g in presence of UV-irradiation, and up to 150 mg/g - in the presence of pre-activation, whereas the influence of ultraviolet on montmorillonite is noticeably lower. |
