Photoelectrochemical water oxidation on photoanodes fabricated with hexagonal nanoflower and nanoblock WO3†
Abstract
Hexagonal nanoflower WO3 arrays have been prepared by using RCOO− as the structure directing agent in the microwave-assisted hydrothermal synthesis process. The photoelectrochemical performance of the synthesized hexagonal flower-like WO3 electrode was enhanced compared with the block-like WO3 film.
