| Abstract Scope |
Nanostructured metal oxides and their composites play crucial roles in environmental remediation and energy conversion. These metal oxide nanostructures can be synthesized through thermal or anodic oxidation of pure metal foils and their corresponding alloys, offering tunable morphologies and properties. In this talk, I will present the fabrication of various metal oxides derived from both elemental metals and alloy systems. Their functional applications will be discussed with a focus on photocatalytic reduction of heavy metals, hexavalent chromium (Cr (VI)), a highly toxic pollutant of significant environmental concern, as well as their performance in photoelectrochemical water splitting. Furthermore, by integrating graphene oxide and reduced graphene oxide onto these nanostructured metal oxides, the structural-property are improvement are achieved, leading to enhanced charge transport and interfacial activity, which enable improved catalytic and photoelectrochemical performance. |
