Biomimetic synthesis of nanostructured WO(3) · H(2)O particles and subsequent thermal conversion to WO(3)
Nanostructured tungsten oxide (WO(3)) particles were prepared in aqueous solution by mimicking biomineralization. Precursor WO(3) · H(2)O particles were generated by ageing a 60°C (NH(4))(10)W(12)O(41) · 5H(2)O solution containing gelatin. This was followed by heating to 600°C in air for thermal con...

description | Nanostructured tungsten oxide (WO(3)) particles were prepared in aqueous solution by mimicking biomineralization. Precursor WO(3) · H(2)O particles were generated by ageing a 60°C (NH(4))(10)W(12)O(41) · 5H(2)O solution containing gelatin. This was followed by heating to 600°C in air for thermal conversion to WO(3). The addition of gelatin led to the formation of layered structures consisting of WO(3) · H(2)O platy particles, which contained segmented, block-like nanoscale units. The macroscopic layered structure was preserved after thermal conversion to WO(3), while the morphology of the block-like units changed to orthogonally crossed nanorods. |
