The present work investigates the size dependent reflective properties of TiO2 nanoparticles and discusses the development of reflectors. The nanocrystalline TiO2 powders with different crystallinity and phase structures were obtained by controlling the reaction parameters. TiO2 nanoparticles synthesized via sol-gel method were characterized by using X-ray diffraction (XRD), transmission electr...

Well-defined olive-shaped Bi(2)S(3)/BiVO(4) microspheres were synthesized through a limited chemical conversion route (LCCR), where olive-shaped BiVO(4) microspheres and thioacetamide (TAA) were used as precursors and sulfur source, respectively. The as-synthesized products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution trans...

The polycrystalline SrTiO3 thin films were prepared by the sol-gel-hydrothermal method on glass substrates. synthesis pathway was initiated preparing a clear TiO2 solution using sol-gel method. This then deposited substrate dip coating technique, followed transformation of layer into hydrothermal crystal structure, bond interactions, and band gap energy layers characterized X-ray Diffraction (X...

The photocatalytic activity of meso-tetraphenylporphyrins with different metal centers (Fe, Co, Mn and Cu) adsorbed on TiO(2) (Degussa P25) surface has been investigated by carrying out the photodegradation of methyl orange (MO) under visible and ultraviolet light irradiation. The photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectan...

Samarium-doped ZnO hierarchical micro/nanospheres (Sm/ZnO) were synthesized via a facile and surfactant-free chemical solution route. The obtained products were characterized by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), UV–visible diffuse reflectance spectroscopy (UV-vis DRS) and photolumi...

CdIn2S4 was prepared by ultrasonic spray pyrolysis. The prepared CdIn2S4 was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FSEM), transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy (UV-Vis DRS), and N2-sorption techniques. Aqueous photocatalytic activity was evaluated by the decomposition of methyl orange under visible li...

A novel photocatalyst based on TiO2-PANI composite supported on small pieces of cork has been reported. It was prepared by simple impregnation method of the polyaniline (PANI)-modified TiO2 on cork. The TiO2-PANI/Cork catalyst shows the unique feature of floating on the water surface. The as-synthesized catalyst was characterized by X-ray diffraction (XRD), scanning electron micrograph (SEM), t...

Various nanocomposite materials play a number of important roles in modern science and technology including pharmaceutical science. Among these materials, mesoporous materials cover a large number of applications in drug delivery system. The quantitative incorporation and high dispersion of selenium nanoparticles into MCM-41 have been made possible by the coordination between Se(IV) ion and ami...

A Ce0.3TiOx oxide carrier was synthesized via a sol-gel process, and Ce0.3TiOx supported metal (M=Cd, Mn, Fe, W, Mo) oxide catalysts were prepared by the method of incipient-wetness impregnation. The catalysts were characterized by means of X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transfor...

molecular sieves mcm-41 were synthesized from rice husk ash (rha) as alternative sources of silica. the material was synthesized by a room temperature method from a gel with the molar composition sio2: 1.6ea: 0.215hdtmabr: 325h2o with ph correction. the cetyltrimethylammonium bromide (ctmabr) was used as a structure template. nanocomposite containing 5.0 and 10.0 wt.% of cu was synthesized unde...
