Hierarchical nanostructures are very universal in the natural world. However, to date most of synthetic approaches are just capable of producing simple nanomaterials, such as nanospheres, nanorods, nanowires, nanopolyhedrons, etc. Fabrication of complex nanostructures has to depend on the assembly of single nano-building blocks and e-beam lithography. Thus, it is imperative to create complex nanostructures...
Tungsten trioxide (WO3) thin films were prepared on fluorine-doped tin oxide (FTO) substrate by electrodeposition method using peroxotungstic acid with pH 1.3 as the electrolytes. The as-deposited sample was calcined at 350°C. The gold (Au) loading on WO3 films was carried out by using the sputtering method with a different sputtering time of 1s and 5s. The photoelectrochemical activities of bare...
