Semiconductor photocatalysis has been intensively studied in recent decades for a wide variety of application such as hydrogen production from water splitting and water and air treatment. The majority of photocatalysts are, however, wide band-gap semiconductors which are active only under UV irradiation. In order to effectively utilize visible solar radiation, this thesis investigates various t...

The subject of this research work was to analyze the structural and morphological changes TiO2 as a result incorporation CNTs interpret underlying principles for observed interactions. Hybrid TiO2/CNTs nanostructures were prepared by simplified sol-gel method followed monitoring thermally-induced alterations occurring up 400 ºC. effects different type (activated MWCNTs SWCNTs) well variation co...

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...

A series of CuO-Cu2O/TiO2 nanocomposite samples were prepared by the sol-gel method. Before applying the sol-gel method, the Cu(OH)2 nanostructure on Cu powders were formed by in-situ solution treatment. The samples were characterized through some techniques and the photocatalytic performance of CuO-Cu2O/TiO2 nanocomposites for gas-phase 2-propanol photo-oxidation under UV and sunlight type ill...

Carbon nanotubes (CNTs), due to mechanical, electrical, and surface area properties their ability adapt different nanocomposite structures, are very substantial in supercapacitor electrodes. In this review, we have summarized high-performance, flexible, symmetry CNT supercapacitors based on the CNTs/graphene, CNTs/metal, CNTs/polymer To present recent developments supercapacitors, discuss perfo...

This study presents functionalized carbon nanotubes (CNTs) decorated with barium titanate (BT) (denoted as BT@CNTs) via hydrothermal and self-assembly methods to improve dispersion in polypropylene (PP) matrix enhanced thermal, mechanical, thermomechanical properties. The CNTs, BT, BT@CNTs the addition of maleic anhydride (PPMA) compatibilizer were used fabrication PP based nanocomposites for t...

Porous TiO2/C nanocomposite shells with high capacity, excellent cycle stability, and rate performance have been prepared. The synthesis involves coating colloidal TiO2 nanoshells with a resorcinol-formaldehyde (RF) layer with controllable thickness through a sol-gel-like process, and calcining the composites at 700 °C in an inert atmosphere to induce crystallization from amorphous TiO2 to anat...

Synthesis and characterization of Cd-TiO2/PEG/FA nanocomposite as a biomaterial is the main aim of this research. Cd-doped TiO2 nanoparticles (NPs) were synthesized by solvothermal assisted sol-gel method. Then, polyethylene glycol (PEG) was added to the as-synthesized NPs in order to modify their surface and to prevent agglomeration. In the next step, folic acid (FA) was conjugated to Cd-TiO2/...

in this research we have developed a treatment method for textile wastewater by tio2/sio2-based magnetic nanocomposite. textile wastewater includes a large variety of dyes and chemicals and needs treatments. this manuscript presents a facile method for removing dyes from the textile wastewater by using tio2/sio2-based nanocomposite (fe3o4@sio2/tio2) under uv irradiation. this magnetic nanocompo...

This study investigates the preparation of InSb-added TiO2 nanocomposite films by RF sputtering. The optical absorption spectra are obviously shifted to visible and near-infrared regions. High-resolution transmission electron microscopy indicates that sphere-shaped InSb nanocrystals with a size of about 15 nm are dispersed in a matrix. The X-ray diffraction result reveals that the matrix forms ...
