Development of novel nanoporous hexagonal tungsten oxide membrane for separation of water/acetic acid mixtures via pervaporation

A novel nanoporous hexagonal tungsten oxide (NP-h-WO3) membrane was developed for separating water/acetic acid (H2O/AcOH) mixtures. The nanopores on the c-plane of h-WO3 are larger than H2O molecules and smaller than AcOH molecules and thus should allow for their effective separation. Moreover, h-WO...

Zusammenfassung:A novel nanoporous hexagonal tungsten oxide (NP-h-WO3) membrane was developed for separating water/acetic acid (H2O/AcOH) mixtures. The nanopores on the c-plane of h-WO3 are larger than H2O molecules and smaller than AcOH molecules and thus should allow for their effective separation. Moreover, h-WO3 exhibits high stability in acids (pH
