In past decades, mankind has embarked on an unprecedented and remarkable growth in industry that has led to a more prosperous lifestyle for the people of many countries. And in many developing countries, such explosive industrial growth is just now beginning to raise the living standards of the people. However, most industries, especially in these developing countries, are still powered by the burning of fossil fuels so that the lack of clean energy resources has caused environmental pollution also on an unprecedented, huge global scale. Toxic wastes have been relentlessly released into the air and water, leading to serious and devastating environmental and health problems while endangering the planet itself with the effects of global warming. To address these urgent issues, new catalytic and photo-catalytic processes and open-atmospheric systems, which can operate at room temperature and are totally clean, safe and efficient, and thus environmentally harmonious are presently being developed. In particular, highly functional photo-catalytic processes that can utilize not only UV but also with visible light will be essential in technologies that can harness the abundant solar energy that reaches the earth. Titanium oxide-based catalysts are especially promising as one of the most stable, nontoxic, easily available photo-functional materials known today.     Because of their high application potential porous materials since the early 20th century in the research focus. Biological, physical and chemical processes often require materials with defined internal and external structure as well as defined pore sizes.  Indeed, well controlled and diversified processing strategies are the key to the production of highly porous ceramic components that could be used in a wide range of applications such as support for catalyst, in mixing and separation technologies or as support for heat storage materials. Glass is an inorganic non-metallic materials which is being used in numerous applications like, glazing, beverage containments and optical applications. Cellular glass structures can be utilized in fluid dynamics for as a catalyst barriers or as support for microbial biomass or enzymes. The light driven activation of the supported component becomes feasible due to material optical transparency. The UV-light or high energy part of visible spectrum can be used for light activation. Hence the cellular material support must be transparent enough within this specific wave length range to use sun light as a radiation source.In past years, research is done on developing optical semitransparent glass foams using preceramic polymers through a unique manufacturing route.
