Abstract
Abstract Microporous aluminomethylphosphonate AlMepO-β was prepared at 100–160°C in steam-assisted conversion (SAC) method from dry gel precursors. The sizes of the obtained crystals were considerably smaller compared with those prepared in hydrothermal method. By applying the SAC method to film preparation, a 40 μm-thick film-like polycrystalline layer of AlMepO-α was obtained on a porous alumina substrate. The layer was composed of many separate domains of ca . 200 nm in size, which are needle-like crystals.
