Titanium dioxide as a photocatalyst to create self-cleaning concrete

نویسندگان

چکیده

The use of Titanium Dioxide (TiO2) in the form Ultrafine particles as a coating for concrete pavement have received considerable attention recent years these can trap anti compose organic and inorganic air pollutant by photocatalytic process. In spite promising benefits, durability resistance to wear coatings has not been evaluated. objective this study is determine effect on with spectrophotometer its environment. We prepared samples varying % TiO2 checked strength, ability resist radiations compared their results normal concrete.

Hydrogen Reduced Rutile Titanium Dioxide Photocatalyst

For TiO2 photocatalysts, recombination of photoexcited electrons and holes would occur in crystalline defects such as oxygen vacancies, Ti ions, and surface states. Therefore, it is believed that the density of crystalline defects should be decreased to improve the photocatalytic activity of TiO2 particles. Contrary to this common knowledge, the introduction of crystalline defects by hydrogen r...

An environmental friendly solution for air purification and self-cleaning effect: the application of TIO2 as photocatalyst in concrete

Heterogeneous photocatalysis is a rapidly developing field in environmental engineering. It has a great potential to cope with the increasing pollution by traffic. The addition of a photocatalyst to ordinary building materials such as concrete, creates environmental friendly materials by which air pollution or pollution of the surface itself can be diminished. TiO2 is added to a cement mortar i...

Nickel(II) oxide surface-modified titanium(IV) dioxide as a visible-light-active photocatalyst.

The electronic modification of TiO(2) with highly dispersed NiO particles smaller than ca. 2 nm by the chemisorption-calcination-cycle technique has given rise to a high level of visible-light-activity exceeding that of iron oxide-surface modified TiO(2) simultaneously with the UV-light-activity being significantly increased.

Self-cleaning ability of a photocatalyst-containing denture base material.

This study examined the ability of a photocatalyst mixed in a denture base resin to decompose organic substances which adhered to the denture base resin surface. The photocatalyst was mixed with denture base resin at concentrations of 0, 5, 10, and 15% (w/w). Decomposition test, bending test, and surface roughness measurement were performed at 1, 7, 30, 90, and 180 days after polymerization. De...
