There are other technologies applied in electronic air cleaning systems such as UV, UV with photocatalysts
, non-thermal plasma, and ozone generators, which utilize oxidation mechanisms for the removal of VOCs [Urashima and Chang, 2000; Zhang et al.
Compared to using photocatalyst
material as-is, this technology more than doubles the usable amount of light that can be gathered from sunlight, and increases by more than a factor of 50 the surface area of the material that can react with water.
The photocatalytic activity of the sample did not decrease significantly after five successive cycles of degradation tests, indicating that the photocatalyst
was fairly stable under the conditions used in this study.
Batzill, "Why is anatase a better photocatalyst
Semiconductor particles are ideal photocatalysts
for photocatalytic reaction.
The biocidal efficiency was proportional to the specific surface area of photocatalysts
and the quantum yield of photocatalytic system because the number of O[H.
In this study a concrete surface coated with LiNbO3 is used as a photocatalyst
that can absorbs light and using that energy, it can chemically convert CO 2 and water into formic acid and oxygen.
Titanium dioxide, as a cheap, nontoxic, and highly efficient photocatalyst
, has been extensively applied for degradation of organic pollutants, for air purification, as a deodorant, for sterilization, and as a demister (Linsebigler et al.
Other applications include sunscreen , skincare products , toothpaste , food additive , semiconductors , and more recent as photocatalyst
for the oxidation reaction of water [9-15].
In addition, SDK has been developing many plant-factory related products that support realization of optimum environment for high-speed plant growth and productivity improvement of plant factories, including LED lighting equipment, aluminum racks for plant cultivation, and heat insulation panels coated with antimicrobial photocatalyst
The core of the technology is the UV-activated nano-particulate titanium dioxide (Ti02) photocatalyst
1-15 wt% of a photocatalyst
in the exposed surface.
