Title : Electrocatalytic materials for fuel oxidation and oxygen reduction reactions


mprovements in the design and function of catalytic materials are crucial in solving a host of current problems including developing cleaner fuel technologies and removing environmentally harmful processes in the pharmaceutical or chemical industries. By far the most extensive industrial usage of composite materials relates to polymeric matrices reinforced with glass or carbon fibres. These form the mainstay of many important application areas in aerospace, land transport, marine, sports goods and a number of other industrial sectors. In general, these materials are mature and highly-developed,however researchers tend to focus on the composites, designed for more specialised applications. Catalytic materials are those solids that allow the chemical reaction to occur efficiently and cost-effectively. In recent years, many different catalytic materials are being studied for various catalytic processes. Porous materials consisting of organic linkers connected by metal ions provide framework scaffolds for heterogeneous catalysis, which is based on the organic, or inorganic components. Composite materials prepared by the combination of two or more different materials with distinct chemical or physical characteristics for fuell cell reactions. Various metals’ containing coatings and thin solid films for corrosion resistance analysis and for investigation of others electrochemical reactions. This work presents investigation of various carbon based catalytic materials containing noble and non-noble metals and their oxides for fuel cell reactions. Various Au, Pd, Co and Co3 O4 , CeO2 , Nb2 O5 supported materials using different fabrication methods such as microwave irradiation heating, electroless deposition and adsorption were prepared. Electrocatalytic properties of obtained AuCo3 O4 /C, PdCo3 O4 /C, AuCeO2 , AuNb2 O4 , CoCo3 O4 /C materials were investigated towards fuel (methanol, ethanol, ethylene glycol) oxidation and oxygen reduction reactions and discussed on the basis of electrochemical data.


Dr. Virginija KepenienÄ— got her PhD degree in 2012 at the Department of Catalysis of Center for Physical Sciences and Technology. After a post-doctoral internship related to the investigation of catalysts for alkaline fuel cells she continued her work as a researcher at the same Department in relation to the various nano-scale materials formation and investigation. She has been working as a senior researcher since 2017. Virginija KepenienÄ— actively participates in scientific activity.
