PHOTOCATALYSIS TECHNOLOGY
ECO FRIENDLY ■ SAFE ■ SUSTAINABLE
PHOTOCATALYSIS TECHNOLOGY
The technology of photocatalysts is mainly applied for creating layers of Nano thickness comprise of photocatalyst solutions on surfaces of inorganic or organic nature.
The chemical functionality of photocatalyst layer is actually empowered by either sun’s rays or UV lights at the molecular level against the adjacent layer of surrounding atmosphere as it breaks down bacteria, viruses and other harmful substances, various dirt and harmful odors just by direct contact.
PHOTOCATALYST SAFETY
One significant compounds of photocatalysis materials is Titanium Oxide TiO2. It can be highly catalyzed by light rays. Since TiO2 is fairly light by atomic number, environmentally friendly as it is also
lustrous transition metal with a silver color, low density, and high
strength, resistant to corrosion in seawater & Aqua Regia, chlorine, Tio2 compound of photocatalysis is safe & does no harm to human health.
PHOTOCATALYST SUSTAINABILIY
The chemical decomposition of TiO2 catalyst in photocatyst layer
functions repeatedly by the exposure to suitable light rays. Hence the chemical functionality of photocatalyst layer can be sustained by the availability of light.
BRIEF INTRODUCTORY
NANO TECHNOLOGY & PHOTOCATALYSIS PHENOMENON
Dr. Norio Taniguchi
Dr. Norio Taniguchi presented this paper of nanotechnology concept in the first ICPE conference of 1974. He coined the term nano-technology in 1974 to describe semi conductor processes.
Nano Meter
such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer-nanotechnology- mainly consists of the processing of separation, consolidation, and
Nano Technology
deformation of materialsby one atom or one molecule.
A brand new term of “nanotechnology” at that time has become so popular and common today.
Photosynthesis Phenomenon
Dr. Takao Kan
In fact, photosynthesis was originally introduced in the scientific research paper published on the topic of photosynthesis in 1965 by the pharmacology specialist in the college of chemistry science in Tokyo University, Professor Kan Takao.
Dr. Honda & Fujishima
In 1967, an experiment concerning photocatalyst Tio2 was conducted by Dr. Honda & Dr. Fujishima in Tokyo University. It was published in “Journal of Industrial Chemistry” in 1969 and in the “Journal of Industrial Chemistry” in 1969.
Honda Fujishima Trail
This experiment was named “Honda Fujishima Trail” and was, indeed, the foundation of discovering high efficacy, safety of use and continuous structural stability features of “Titanium Oxide” in comparison with other photocatalysts.
