Method for Mesoporous Materials |

Mitsubishi Chemical Corporation (MCC; Head Office: Chiyoda-ku, Tokyo; President:
Kanji Shono) has recently developed new method to manufacture mesoporous materials
which contain highly controlled pores of 2 to 50 nanometer. Since our manufacturing
process does not use "template", which was considered essential component
for production of mesoporous materials, it becomes possible to produce them at
relatively low cost. MCC will sell this mesoporous materials and develop the use
of these materials in wide-ranging application fields in the future.
According to the international standard, IUPAC, the pore with a diameter of 2
to 50 nanometers is defined as mesopore, that with a diameter of over 50 nanometers
as macropore and that with a diameter of less than 2 nanometers as micropore.
Therefore, developed production method is a part of nano-technologies
Since Mobil Oil Corp. of the US has developed mesoporous molecular sieves in 1992,
meso-porous materials have attracted people's attention and various usages of
the materials have been developed. However, since the production of the materials
has to use an expensive template to realize a sharp pore size distribution, industrial
use of the materials has been limited due to high production cost.
MCC's new production method enables the customers to obtain a custom-made pore
size (by 1 nm) with sharp pore size distribution. Our mesoporous material enables
to introduce nano-molecules and nano-particles into pores. In addition, by realizing
the high purity of the materials, it has greatly reduced the changes of the structure
and physicochemical properties of the material at even severe use. Furthermore,
since the production does not use template, which was indispensable for producing
mesoporous materials, it can be produced at lower cost than in the past.
Possible usage of this mesoporous material covers such a wide-ranging application
fields as various types of catalysts, separation materials, adsorbents, printing
materials, surface modifier for plastic films, etc.
By the way, MCC will exhibit the mesoporous materials at the "Inchem Tokyo
2001" which will be held at Tokyo Big Sight (Ariake, Tokyo International
Exhibition Hall) from November 27 through 30 this year.
