Chemist, examine the solar energy and air purification

Wednesday, August 03, 2011
Ample daylight is undoubtedly city break make happy this summer, but those who on their tans are not the only beneficiary. The Sun's rays are also an important part to go green.

Solar lamp can be used to help to clean air and water and produce valuable chemicals that contribute to energy efficiency. Rutgers-Camden Professor says everything, what by a process called Photocatalyst is possible.

"Photocatalyst is a chemical reaction, which under the influence of solar light, appearance," says Alexander Samokhvalov, Assistant Professor of chemistry at Rutgers-Camden. "I'm examines the fundamental chemistry of reactions such as sunlight is to go."

In particular, the chemist examined how water components with sunlight and a solid Photocatalyst is split into hydrogen and oxygen. Production of hydrogen vehicles is an example of a "green" application, however, the default allocation is water.

Samokhvalov is the recipient of the Cottrell Science Award by Research Corporation for Science advancement. The Foundation supports innovative scientific research and the development of academic scientists.

In addition to the two - year$ 45,000 Cottrell award Samokhvalov received a $5,000-scholarship of the Rutgers University Research Council for his work with Photocatalyst.

Photocatalyst technology will receive attention as immediate means to reduce urban air pollution. Samokhvalov says, examples for come this technology at work are dirt in sunlight and portable air purifiers such as the one that sits in Samokhvalovs Office on the campus of Rutgers-Camden self-cleaning Windows, which break down chemically adsorbed amount.

In both cases is the Photocatalyst titanium dioxide or TiO2, that often absorb in sunscreens due to the possibility of UV light. Samokhvalov says that TiO2 used to remove ultraviolet light or break harmful air pollutants.

Exposure to sunlight the titanium dioxide reacts with pollutants into the air or water and breaks them down into harmless substances. The connection has other applications when used as a photocatalyst, clean as the conversion of greenhouse gas into liquid fuels.

"By change and we can further development of this technology, continue to reduce pollution in our air and water," says the Rutgers-Camden chemistry scholars. "But what is missing in many research on Photocatalyst acute, is, like the electrons in solid Photocatalyst actually in the absorption of light to drive chemical reactions behavior." "This is something that I want to examine."

He continues, "It's somewhere far from the place where the photon was actually recorded that fundamental interest to understand if electron transfer in the immediate vicinity of the atom, which absorbs the energy of a photon, or where the chemical reaction." "Modern scientific instrumentation, can answer this question a little bit of imagination and work in the lab."

Cottrell Science Award includes funding a research scholarship undergraduate summer and helps to finance with the purchase of an apparatus used in research.

Samokhvalov has several students with him for the project work.

"I believe that it is important to the interested undergraduate researchers in exploratory experimental work in the entire academic year is employed," he says.

Samokhvalov says "The Cottrell Science Award is a confirmation of the growing importance of Bachelor's research in the chemical industry in the new areas of clean and sustainable energy."
