Fast Synthesis

Fast synthesis of high-silica ZSM-5 zeolite through vapor-phase transport (VPT) method was reported in this paper. The synthesized samples were characterized with XRD, FT-IR, XRF, SEM and N2 Absorption. Factors affecting the synthesis of ZSM-5 zeolite such as the alkalinity, the crystallization temperature and time, the quantity of seeds were investigated. With precipitated silica and fumed silica as silica source respectively, the appropriate ratio was studied as follows: (0.04-0.05) Na2O: 1.0SiO2: 15H2O: (0-0.0046)Al2O3: 0.01Seed, the reaction was carried out at 393-413K for 4-24h.

Under VPT conditions, a dry gel derived from a conventional hydrogel (or an ultrasonically treated hydrogel) can be converted into SAPO-34 crystals around 300–500 nm (or below 100 nm).

A ultrahydrophobic ZnO film was synthesized on the Si substrates by a novel vapor phase transport method. The surface structural properties of as-synthesized ZnO film was characterized using scanning electron micrograph (SEM). The contact angles and the rolling angles on such films were measured through an optical contact angle meter. Wettability studies revealed the films exhibited a ultrahydrophobic behaviour with a higher contact angle of 166.8°±6.8° and lower rolling angle of less than 2°-a water droplet moved easily on the surface. SEM showed that compared with pure smooth nickel surface, a lotus-like structrure with micro-nano hierarchical papillae was obviously observed on the ultrahydrophobic ZnO film surface. Such a speccial surface microstructure may result in the ultrahydrophobicity.
