| Abstract
| - Upon a nonstatic patterning method that employs a metastable air−liquid foaming process, macroporousvanadium oxide scaffolds have been synthesized. By controlling the foams liquid fraction, the process inuse allows one to tune the size and shape (from spherical to a more polygonal aspect) as well as thePlateau-borders thickness of the vanadium oxide macroscopic void spaces. XRD experiments reveal theamorphous character of the vanadium oxide matrices intercalated with surfactant entities, while the localstructure around vanadium atoms, as demonstrated with 51V NMR MAS experiments, is close to thatobtained for V2O5 xerogel.
- Vanadium oxide macrocellular foams have been generated using an air−liquid foam nonstatic patterning method. This morphosynthesis strategy allows strong control over macroscopic cell morphologies. The as-synthesized vanadium oxide foams depict an amorphous character with a local order close to that of V2O5 xerogel.
