in this research, a sol-modified composite electrodeposition technique that combines the sol-gel method with the conventional electrodeposition process was utilized to deposit ni-tio2 nanocomposite coatings. cyclic voltammetry and chronoamperometry techniques were applied to study the influence of the tio2 sol concentration on the deposits’ electrochemical behavior. the results clearly showed t...

With a dramatic rise in complexity, needs of nanotoxicology research go beyond simple forms of nanomaterials. This study compared the phototoxicity of nano-TiO2 and graphene-TiO2 nanocomposite (GNP). GNP was synthesized based on a hydrothermal method, which simultaneously performed the reduction of graphene oxide and nano-TiO2 loading. A series of acute toxicity tests of nano-TiO2, graphene and...

Nanocomposites based on TiO2-supported copper nanoparticles were prepared by a hydrothermal method where copper nanoparticles with or without the passivation of 1-decyne were chemically grown onto TiO2 nanocolloid surfaces (and hence denoted as CuHC10/TiO2 and Cu/TiO2, respectively). Transmission electron microscopy measurements showed that the size of the hybrid nanoparticles was 5-15 nm in di...

Photocatalytic removal of water and air pollution has received much attention today. Many photocatalysts based on semiconductors have been developed used. Binary even ternary composites to solve the drawback semiconductors, including high band gaps short life time charge carriers. In this study, a three-component composite TiO2/CuO/WO3 was synthesized by adding WO3 TiO2/CuO. Their structural pr...

one of the most important applications of carbon nanotubes (cnts) is as reinforcement of metal matrix composites, because of their excellent mechanical properties. in this study, al-tio2-multi walled carbon nanotubes (mwcnts) nanocomposite is fabricated using isostatic pressing followed by hot extrusion. mechanical alloying is used to mix powders of aluminium, tio2 and mwcnts. tio2 with the amo...

This article contains the dataset referring to the article "Study of the effect of the dispersion of functionalized nanoparticles TiO2 with photocatalytic activity in LDPE" (Jahell et al., 2016) [1]. It includes the FT-IR data of the functionalized nanoparticles of TiO2 with Hexadecyltrimethoxysilane in different degrees of functionalization, thermogravimetric analysis, distribution and particl...

Herein, we use a facile procedure to graft a thin graphitic C3N4 (g-C3N4) layer on aligned TiO2 nanotube arrays (TiNT) by a one-step chemical vapor deposition (CVD) approach. This provides a platform to enhance the visible-light response of TiO2 nanotubes for antimicrobial applications. The formed g-C3N4/TiNT binary nanocomposite exhibits excellent bactericidal efficiency against Escherichia co...

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...

TiO2/Cu2O/CuO multi-nanolayers highly sensitive toward volatile organic compounds (VOCs) and H2 have been grown in various thicknesses by a cost-effective reproducible combined spray–sputtering–annealing approach. The ultrathin TiO2 films were deposited spray pyrolysis on top of sputtered–annealed Cu2O/CuO nanolayers to enhance their gas sensing performance improve protection against corrosion ...

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...
