Preparation and Catalytic Properties of Ti-SBA-15 Mesoporous Materials
Ti-SBA-15 mesoporous materials were directly synthesized via a hydrothermal process and characterized by using nitrogen adsorption-desorption measurements, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, diffuse reflectance ultraviolet-visible spectroscopy, and infrared ray spectroscopy. The effect of synthesis temperatures on the structure and catalytic effic...
متن کاملPhoto-Catalytic Properties of TiO2 Supported on MWCNTs, SBA-15 and Silica-Coated MWCNTs Nanocomposites
Mesoporous silica, specifically SBA-15, acid-treated multi-walled carbon nanotubes and a hybrid nanocomposite of SBA-15 coated onto the sidewalls acid-treated multi-walled carbon nanotubes (CNTs) were prepared and used as supports for anatase TiO2. Sol-gel methods were adapted for the synthesis of selected supports and for coating the materials with selected wt% loading of titania. Physical and...
متن کاملPyrrolidone-modified SBA-15 supported Au nanoparticles with superior catalytic properties in aerobic oxidation of alcohols.
Au nanoparticles with small sizes (2-3 nm) were effectively stabilized in the mesopores of (S)-(-)-2-pyrrolidinone-5-carboxylic acid-modified SBA-15, which showed superior catalytic properties in aerobic oxidation of alcohols, compared with pyrrolidone-free SBA-15 supported Au catalysts.
متن کاملEffect of Preparation Methods and Pluronic Template on the Catalytic Activity of Ca/SBA-15
Two approaches for metal ion incorporation were employed to introduce Ca2+ into SBA-15; Direct Synthesis (DS) and Wet Impregnation (WI). The non-ionic template was removed by two different methods; calcination and solvent extraction. The obtained catalysts were characterized by means of X-Ray Powder Diffraction (XRD), Energy Dispersive X-ray (EDX), and FT-IR spectroscopy. The bas...
متن کاملSynthesis, characterization and catalytic application of Fe3O4@Cys–SO3H for preparation of 2H-indazolo[1,2-b]phthalazine-triones
The surface ofFe3O4 magnetic nanoparticles (MNPs) was modified by L-cysteine through condensation of COOH groups of L-cysteine and OH groups on the surface of Fe3O4. The –SH group of preparedFe3O4@Cys MNPs oxidized to –SO3H group and Fe3O4@Cys–SO3H as an environmentally friendly ...
