SDK Subsidiary Develops Titanium Oxide Fine Particles with High Photocatalytic
Activity 
Tokyo, Oct 16, 2012 - (JCN Newswire) - Showa Titanium Co., Ltd., a consolidated
subsidiary of Showa Denko K.K. (SDK), has developed titanium oxide fine
particles for use in UV-light-responsive photocatalyst with highest-level
activity.  The product has been developed as part of a project sponsored by the
New Energy and Industrial Technology Development Organization (NEDO).  Showa
Titanium is conducting tests for volume production at its pilot plant, aiming
to commercialize the product by the end of 2013. 
Photocatalyst accelerates specific chemical reactions, using light energy.
When used as photocatalyst, titanium oxide causes strong oxidation/reduction
reactions in the presence of UV light, decomposing stains of organic
substances.  It also exhibits ultra hydrophilicity, causing water to spread as
a thin film.  Thus, titanium-oxide-based photocatalyst is expected to
contribute to environmental purification using natural energy, for such
applications as antifogging window glass and antifouling coating for external
walls. 
When titanium oxide particles become finer, their photocatalytic activity
improves.  However, fine particles of titanium oxide often develop crystal
defect, resulting in lower efficiency in the use of light and lower
photocatalytic activity.  Showa Titanium has developed decahedral titanium
oxide fine particles with minimized defect, by applying its gas-phase
technology to produce titanium oxide nanoparticles for ceramic capacitors. 
In addition to promoting the use of the new product in higher-activity
photocatalyst, Showa Titanium will aim to develop new applications in the area
of functional materials, using the advantage of "fine particles with
minimized defect." 
Showa Titanium will introduce this new product at NEDO's forum for
reporting the results of "Project to Create Photocatalyst Industry for
Recycling-oriented Society" to be held at Kokuyo Hall in Shinagawa Ward on
October 25.
