| Abstract Scope |
Scalable formation of metal oxide nanostructures on metallic foils can be achieved via thermal or anodic oxidation. In this talk, a brief outline of the formation mechanism based on different types of metal oxides will be given (Fe2O3, TiO2, Nb2O5). These metal oxide nanostructures, which exhibit large specific surface area serve as good photocatalysts for photoreduction of heavy metal ions such as hexavalent chromium (Cr (VI). Cr (VI) is commonly used in the chrome plating industry and is extremely toxic and hazardous to human beings.
To further explore the structure-photochemical property of hybrid material, decoration of graphene oxide and reduced graphene oxide on TiO2 nanowires obtained by thermal oxidation and their feasible application for photoreduction of Cr (VI) will also be presented. |
