Self-supported tungsten oxide (WO3) foams were synthesized by a combination of sol-gel, electrospinning, and thermal oxidation processes. Mixtures of tungsten isopropoxide (C18H42O6W)-based precursors and cellulose acetate (CA) were electrospun and subsequently heat-treated. Structural characterization of the as-processed foam-like monoliths confirmed that they consist of cubic WO3 nanoparticles in a continuous matrix with open porosity. The formation of the self-supported nano- foams is a result of self-assembly of the composite nanofibers in the non-woven electrospun mats. The cubic WO3 foams have a band-gap of 2.53eV and can be used as visible light photocatalysts.
