Washcoated ceramic monoliths for total oxidation of volatile organic compounds

Project goals

Volatile organic compounds (VOC) are one of the major contributors to air pollution and their emissions are strictly regulated by the directives of European Union. Catalytic oxidation is efficient, cost-effective and environmentally friendly way to treatVOC emissions. In industrial applications, large volumes of gases have to be treated and therefore monolithic catalysts have to be used. This project is focused on the development of monolithic catalysts for total oxidation of VOC based on ceria-zirconia mixed oxide doped by noble metals. Ceramic monoliths are chosen due to their successful application in automotive catalysts and in the industry. The aim of the project is to propose methods for the preparation of highly active and selective monolithiccatalysts and to develop the strategy for their tailored synthesis. The knowledge on activity/selectivity vs. composition/structure relationships of these materials may help to solve important environmental problem.

    Keramické monolity s katalytickou vrstvou pro úplnou oxidaci těkavých organických látek

  • Annotation in Czech

    Těkavé organické látky (VOC) jsou jedním z hlavních přispěvatelů ke znečištění ovzduší a jejich emise jsou přísně regulovány směrnicemi Evropské unie. Katalytická oxidace je efektivní, rentabilní a ekologicky šetrný způsob, jak eliminovat emise VOC. V průmyslových aplikacích musí být ošetřeny velké objemy plynů, a proto musejí být použity monolitické katalyzátory. Tento projekt je zaměřen na vývoj monolitických katalyzátorů pro úplnou oxidaci VOC založených na směsném oxidu ceru a zirkonia dopovaném ušlechtilými kovy. Jako nosič jsou zvoleny keramické monolity kvůli jejich úspěšnému využití v automobilových katalyzátorech a v průmyslu. Cílem projektu je navrhnout metody pro přípravu vysoce aktivních a selektivních monolitických katalyzátorů a vyvinoutstrategii pro jejich syntézu na míru. Znalosti o vztazích mezi katalytickými vlastnostmi, složením a strukturou těchto materiálů mohou pomoci vyřešit důležitý problém ochrany životního prostředí.

  • Project results evaluation

    In agreement with the original aim of the project, new monolitic catalysts of oxidation of volatile organic compounds were prepared and their properties were studied. The catalytic noble metal layers were deposited either on ceramic support or on the support of polymer nanofibers. The results were published in 4 papers in impacted journals and one additional paper is still under review.
