the transformation of the nanoparticles into the rutile modi cation. It was shown

that this TiO 2 -loaded glass foam performed better than TiO 2 nanoparticles in
mineralizing methylene blue (3,7-bis(dimethylamino) phenazathionium chloride)
which was used as a model substance to demonstrate the high catalytic performance
as an environmental catalyst to clean contaminated water.

3 Summary, Conclusions, and Perspective

In this contribution, we have shown that ceramics are used in a wide range of
sustainable technologies and are poised to play an ever-increasing role in these
emerging technologies. This is in part due to their ability to withstand high tem-
peratures and aggressive chemical environments, their high hardness, and their high
wear resistance. However, a continuing challenge in the increased use of ceramics is
the challenge in manufacturing of ceramics. The process that we discuss in detail in
this paper, polymer-derived ceramics, addresses this central challenge of ceramics.
Over the years, a variety of techniques have been developed to make ceramic

bers,
coatings, and porous ceramics. An overview of these approaches is provided.
Due to the ability to make a wide variety of desirable forms, the ability to control
the composition and purity, and the ability to make unusual micro- and nano-
structures, ensures that this approach will provide differentiating solutions to the
challenges offered by the emerging sustainable technologies.
