Toru Wakihara and Tatsuya Okubo

Zeolites have been widely utilized in industry and in household products, for example as adsorbents, ion-exchangers, andcatalysts, and have attracted considerable attention as host materials for various nanotechnology applications. Recent devel-opments in analytical methods have enabled detailed studies on the crystallization mechanism of zeolites. The purpose of thisreview is to give a survey of recent progress in hydrothermal synthesis and characterization of zeolites.

282 Chemical Recycling of Polycarbonate to RawMaterials by Thermal Decomposition withCalcium Hydroxide/Steam

When Ca(OH)2 was added to PC at 500 °C,the yield of the low boiling fraction increased irrespective of the existence of steam. When themolar ratio (Ca(OH)2/PC) was 0, the yield of the low boiling fraction at a steam concentration of 86 vol % was 17 wt %, and at the molar ratio (Ca(OH)2/PC) of 5 was 31 wt %, the yield of thehigh boiling fraction was 67, 49 wt %, respectively.Moreover, the addition of Ca(OH)2 led to a high selectivity for phenol (70 mol %) irrespective of steam concentration.

284 Phosphor-doped Titania —a Novel Photoca-talyst Active in Visible Light

A novel phosphor-doped titania prepared by a

simple modified sol–gel method shows a

narrower band gap than pure titania and an

absorption tail in the visible range, which

results in its effective photocatalytic

degradation of 4-chlorophenol under

visible-light (>420 nm) irradiation.0 30 60 90 120

Polyaniline/ethylcellulose composite microsphereswere prepared by microencapsulation technique viaa modified emulsion−solvent evaporation method. Thecore was gained through the polymerization of aniline,while the shell was formed by the solidification ofethylcellulose under the condition of the evaporationof organic solvent. Microscopic study showedthat composite particles were all spherical in shapewith micron size. In scanning electron microscopeobservation, it can be seen that the size distribution ofcomposite particles is fairly narrow. The surface ofshell is rough and has some macropores. The structuresof composite microspheres were further characterizedby Fourier transform infrared spectra and UV–visspectra.

396 Controllable Synthesis of One-dimensionalSingle-crystalline TiO2 Nanostructures

The high-magnification TEM and ED images ofas-synthesized titania nanoribbons indicate that thesynthesized nanoribbons are structurally uniform with aninterplanar spacing of about 0.35 nm, which correspondsto the distance between two (101) planes of anatase phaseTiO2. The clear lattice fringes further confirm that thenanostructures are single-crystalline and the structure isperfect.

The amination of toluene to toluidines with hydroxylamine hydrochloride wasinvestigated over vanadium-based catalysts supported on different carriers. Thereaction was carried out in different reaction media with or without the presence ofair. 56% touidine yield with 87% selectivity were obtained at optimized conditions.This provides a new approach in accordance with the trends towards a sustainabledevelopment.

410 Flexible Hexagonal Tube Framework of aNew Nickel Complex Assembled from Inter-molecular Hydrogen Bonds

A new nickel complex with a tubular framework assembly, [Ni(ima)2(MeOH)2]•2MeOH (where ima =4-imidazoleacetato), and its nonmethanolated complex, [Ni(ima)2], have been synthesized. The dried,nonmethanolated compound selectively reacts with methanol to reconstruct the initial porous framework,which induces a porous function connected with the reconstruction of the tubular framework assembly.
