Highly selective, absorbent , free‐standing, paper‐like, highly oriented membranes composed of ammonium vanadium oxide (NH 4 V 4 O 14 ) 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 NH 4 V 4 O 14 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.
