Presentation title:

Towards low-cost integration zinc oxide nanowires in photoanodes

Abstract:

The outstanding properties of semiconductor nanowires (NWs) offer an exciting potential to develop novel and technological advances and new device concepts. For instance, their wide energy bandgap (~ 3.37 eV) and high exciton binding energy (60 meV) make zinc oxide (ZnO) NWs very attractive to develop highly efficient water splitting photoanodes. This presentation will discuss how a low-cost chemical bath deposition is advantaged to produce single-phase wurtzite ZnO NWs. We will show that the ZnO NWs can be doped to fine-tune their energy bandgap and subsequently conformally coated with metal organic framework to yield high-efficiency Photoanodes. The paper will also discuss the ZnO NWs growth, structural and optical characterisation properties and their potential for use as photoanodes for water splitting.
