Inverse opal TiO2 photocatalytsts for environmental applications
This work aims to study the influence that different doping agents can have on the chemico-physical properties of TiO2 synthesized with the task to obtain an ordered porous material with an inverse opal structure and to evaluate the photocatalytic performance of these systems in the degradation of a model dye molecule (Rhodamine B, RhB) in water under Visible light irradiation.
Inverse opal TiO2 as visible-light driven photocatalysts
Semiconductor photocatalysts have attracted a great deal of attention due to their potential application in environmental remediation. Titanium dioxide has been extensively investigated as the most promising photocatalyst. To improve the optical response of TiO2 in the visible region, Inverse Opal TiO2 has been recognized as an efficient photocatalyst due to its unique properties in terms of uniformly ordered and interconnected macroporous architecture.
TiO2-CeO2 based catalysts for photocatalytic oxidation of VOC and water splitting reactions
Photocatalysis with TiO2 is one of the most promising green process for the decomposition of organic pollutants and the hydrogen production . Photo-oxidation of 2-propanol, representative of volatile organic compounds (VOC) and photo-catalytic water splitting for H2 production were investigated over TiO2 catalysts doped with a metal (Au and Ag at 1wt. %) and/or ceria (10 wt.%).
