Cover Picture: Oriented Free-Standing Ammonium Vanadium Oxide Nanobelt Membranes: Highly Selective Absorbent Materials (Chem. Eur. J. 48/2010)

摘要

Highly selective, absorbent, free-standing, paper-like, highly oriented membranes composed of ammonium vanadium oxide (NH₄V₄O₁₄) nanobelts have been created by taking advantage of the nanoscaled self-assembly of the architecture, and exhibit controllable wetting behavior ranging from superhydrophilic to superhydrophobic (when coated with silicone molecules). The as-obtained NH₄V₄O₁₄ nanobelt membranes can selectively absorb a variety of both polar and nonpolar organic solvents; moreover, they can even separate two mixed solvents with very similar polarities and absorb solid contaminants in organic solvents.
