Abstract
Tungsten oxide hollow particle arrays were fabricated for use as the photoanode in photoelectrochemical cells. These arrays were constructed through an electrochemical infiltration method in a three-dimensional colloidal array template. The enhanced contact area between the tungsten oxide and the electrolyte resulted in an increase in photocurrent when compared to a cell prepared with no template. The porous structures were greatly influenced by the temperature used during the thermal annealing step. This simple and cost-effective approach resulted in photocatalytic activity for hydrogen production that was three times higher than that of tungsten oxide prepared without the template.
