Title | Ceramic filter with catalytic coating |
---|---|
Abstract | 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. |

Description of the technology | 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. |
Applications | Technology of composite material can be used for the simultaneous filtration of with organic substances polluted water and decomposition of organic substances. |
Advantages | Main advantages:
|
Technology Readiness Level | Experimental proof of concept |
Partnership offer | The licensing agreement. Consulting agreement at the beginning of production of composite catalytic material and improving properties of produced material |
