Title: Template synthesis of porous titania using cellulose nanocrystals

Abstract

Porous titania with anatase structure has been prepared by a template process with cellulose nanocrystal (CNXL). Air-stable titanium(IV) bis(ammonium lactate)dihydroxide (Tyzor-LA) solution forms Tyzor-LA-CNXL composite upon adding CNXL colloids through interaction between Tyzor-LA and hydroxyl groups of CNXL. The Tyzor-LA-CNXL composite shows rod-like structures of 150-200 nm in length and 5-10 nm in diameter. After calcination at 500oC in air the composite showed anatase with porous structures and 170-200 m2/g specific surface area. X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), FT-IR, scanning electron microscope (SEM), and transmission electron microscope (TEM) were employed to characterize the morphologies and porous structures of the as-prepared and calcined composite mateials.

  • A facile route was presented to fabricate mesoporous anatase titania spheres at low temperature; the titania precursor sphere was prepared through a template-free process and then treated by the boiling water. X-ray diffraction (XRD), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM) were adopted to characterize the morphology and crystal structure of the products. The adsorption properties and photocatalytic activities were also investigated. The results indicated that the porous structure and anatase nanocrystals were gradually formed from the surface to the interior of the titania precursor spheres with increasing treatment time. Moreover, there was little change in themore » size of the spheres during boiling water treatment, thus the size of the mesoporous anatase titania spheres could be easily tailored by controlling the diameter of precursor spheres. The as-prepared product showed excellent adsorption capacity and photocatalytic activity than the commercial P25 due to its high specific surface area.« less
  • In this paper, a simple and efficient methodology for the low-temperature synthesis of phase-pure nanocrystalline rutile TiO{sub 2} with tuned morphology is reported. Control on morphology has been achieved by simple variation of the hydrothermal process, starting with titanium-tetrachloride without using mineralizers, additives or templating agents. The X-ray diffraction (XRD) and selected area electron diffraction (SAED) patterns showed no other phases of TiO{sub 2} establishing the formation of phase-pure rutile titania in the entire temperature range of synthesis (40-150 deg. C) and most noticeably even at a considerably low temperature (40 deg. C). Fourier transform infrared (FT-IR) spectra strongly indicatedmore » the presence of hydroxyl group or surface adsorbed water and the thermogravimetry and differential thermo-gravimetry (TG-DTG) showed no phase change up to 1000 deg. C. A combination of reaction parameters (temperature, time) with a thorough transmission electron microscopy (TEM) study demonstrated the formation of phase-pure rutile titania nanocrystals as nano-rods, bunched nano-spindles or spherical nanoparticles depending on the hydrothermal reaction conditions. The photocatalytic activity of the synthesized nanocrystals has been successfully evaluated on the photodegradation of methyl orange (MO), a well-known pollutant azo-dye, as a model reaction.« less
  • An aqueous-based, inexpensive, TiO2 precursor, Tyzor-LA, and cellulose paper have been used to prepare TiC via carbothermal reduction in an Ar flow. The hierarchical cellulose structures were also completely maintained through the agglomeration of 10-50nm TiC nanoparticles, and the lattice parameter of TiC increased with the increase of reaction temperature, while the oxygen content in the sample decreased (0.24wt% at 1500 C).
  • Monoclinic lead hydrogen arsenate (LHA) nanocrystals with different crystallization morphologies and crystallite sizes were prepared successfully by a soft template synthesis method in the presence of sodium dodecylbenzenesulfonate (SDBS) or polyvinylpyrrolidone (PVP). The products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The possible mechanism of SDBS and PVP in the experiment was briefly illustrated.
  • Porous clay heterostructures (PCHs) were synthesized using natural montmorillonite as a raw material. Apart from pure silica pillars also silica-titania pillars were intercalated into the interlayer space of the parent clay. The detailed studies of the calcination process of the as-prepared PCH samples as well as thermal stability of the pillared structure of these materials were performed. The pillared structure of PCHs intercalated with both silica and silica-titania clusters was found to be thermally stable up to temperatures exceeding 600 deg. C. It was found that titanium incorporated into the silica pillars was present mainly in the form of separatedmore » tetracoordinated cations. For the samples with the higher Ti loading also small contribution of titanium in the form of the polymeric oxide species was detected. Titanium incorporated into the PCH materials significantly increased their surface acidity forming mainly Bronsted acid sites. - Graphical abstract: Synthesis of the montmorillonite based porous clay heterostructures (PCHs) intercalated with silica-titania pillars has been performed. The mechanism of the thermal degradation of organic templates in the pore system of PCHs was studied. PCHs were characterized with respect to structure, texture, composition, surface acidity, thermal stability and form of introduced titanium.« less
