The technology obtaining of ceramic filter with catalytic coating was developed. Composite material is provided for the purification of polluted with organic substances water during filtration process. Carrier of filter contains chemically and thermally stable oxides. Through going pores were formed during formation process of material due to elimination of hydrogen as a result of chemical reaction. Catalytic coatings contain oxides of transition metals such as Fe₂O₃, Co₂O₃, Mn₂O₃, Cu₂O in form of nanosized particles or agregates. Composite material is usable for filtration of hot liquids.

Technology of development of ceramic filter with catalytic coating occurs in two separate steps: 1. obtaining of porous ceramic matrix; 2. Obtaining of the catalytic coating on the matrix. 1.Concentrated suspension of micrometers sized oxides was used for the obtaining of porous ceramic matrix. Through going pore structure of sintered ceramic was provided in the result of elimination of hydrogen during chemical reaction. Sintering process was carried out after solidification and drying green product. 2.Inorganic salts of transition metal and organic acid  were used as raw materials for the obtaining of coated ceramic by extraction-pyrolisis methode.  Nanosized particles of transition metal oxides were formed on the material surface and walls of pores.

Main advantages:

• Simultaneous filtration and decomposition of organic pollutants;
• Possible purification of hot liquiods;
• Possibility partially or fully replase noble metals with transition metal oxide nanoparticles in the catalytic heterogeneous processes.
