photocatalysis

It can also be used for research in photocatalysis (as degradation object).

There are two types of photochemical systems with photocatalysis.

These coatings chemically break down dirt when exposed to light, a process known as photocatalysis.

Other interests include photocatalysis, biomimetic oxidations and ecological chemistry.

Research is being conducted over photocatalysis, the acceleration of a photoreaction in the presence of a catalyst.

This self-cleaning glass has a coating which uses a method of photocatalysis to break down organic dirt with sunlight.

In sunlight, photocatalysis causes the coating to chemically break down organic dirt adsorbed onto the window.

In homogeneous photocatalysis, the reactants and the photocatalysts exist in the same phase.

Disinfection of water by titanium dioxide photocatalysis.

This coating acts to clean the window in two stages, using two distinct properties: photocatalysis and hydrophilicity.

The result is better germicidal effect when it added photocatalysis to the UV tube mounted on the bottom of the robot.

Such synthetic anatases are of considerable interest for photocatalysis and for Grätzel-cell photovoltaics.

The porous channels in MOF structures can be used as photocatalysis sites.

In photocatalysis, the use of mononuclear complexes is usually limited either because they only undergo single- electron process or from the need for high-energy irradiation.

"Theoretical work in photocatalysis has been going on since the 1980s," said Enrico Borgarello, Italcementi's director of research and development.

The conversion of solar energy to hydrogen by means of photocatalysis is one of the most interesting ways to achieve clean and renewable energy systems.

A less-toxic alternative to tin and copper-based antifouling marine paints, ePaint, generates hydrogen peroxide by photocatalysis.

Brookite occurs rarely compared to the anatase and rutile forms of titanium dioxide and, unlike these forms, exhibits no Photocatalysis activity.

It has been suggested that anisotropic staggered gap (type II) nanoscale heterojunctions may be used for photocatalysis, specifically for water splitting with solar energy.

Solar photocatalysis using TiO nanocrystals removed various refractory pollutants, such as phonls, 4-chlorophenol, nitrobenzene, 2-chlorobenzoic acid and hydrobutanedioic acid.

Decontamination of water with photocatalysis and adsorption The removal and destruction of organic contaminants in groundwater can be addressed through the impregnation of adsorbents with photoactive catalysts.

Advanced Energy Materials is a peer-reviewed scientific journal covering energy-related research, including photovoltaics, batteries, supercapacitors, fuel cells, hydrogen technologies, thermoelectrics, photocatalysis, solar power technologies, magnetic refrigeration, and piezoelectric materials.

Heterogeneous photocatalysis is a discipline which includes a large variety of reactions: mild or total oxidations, dehydrogenation, hydrogen transfer, O-O and deuterium-alkane isotopic exchange, metal deposition, water detoxification, gaseous pollutant removal.

Recombination of the electron-hole pairs needed for photocatalysis can occur with any catalyst and is dependent on the defects and surface area of the catalyst; thus, a high degree of crystallinity is required to avoid recombination at the defects.

These reactions have been proven more efficient than the other photocatalysis but the disadvantages of the process are the low pH values which are required, since iron precipitates at higher pH values and the fact that iron has to be removed after treatment.
