Summary in Hungarian
A jelen project fő célja vezető polimerekből és réteges szerkezetű szervetlen vegyületekből létrehozható nanokompozitok előállítása és sokoldalú vizsgálata, valamint a gyakorlati hasznosítás lehetőségének keresése főként az elektrokatalízis területén beleértve a tüzelőanyag-cellák hatékonyabbá tételét is. Ezek a nanokompozitok igen érdekes, újszerű tulajdonságokat mutatnak, amelyek a két különböző komponens közötti kölcsönhatásokra vezethetők vissza. Előkísérleteink során már bizonyítottuk, hogy a-RuCl3-ban az anilin illetve a pirrol interkelációs polimerizációja megy végbe. A RuCl3 mellett más, réteges felépítésű szervetlen vegyületeket, ilyen pl. V2O5 is tanulmányozni kívánunk. Továbbá nanokompozitokat hoznánk létre megfelelő monomerek elektropolimerizációjával oxidokon (pl. TiO2, SiO2), valamint szén nanocsövekben. Biotüzelőanyag-cellákban illetve bioszenzorokban való hasznosításra polimer-mediator-enzim, fotoelektrokémiai célra pedig polimer-fotokémiai reakcióra képes vegyület kompozitok előállítása is szerepel terveinkben. Az interkelációs és ioncsere-folyamatok vizsgálatának fő eszköze az elektrokémiai kvarckristály nanomérleg, az elektrokatalitikus aktivitás megállapításának pedig a forgó gyűrűs korongelektród (RRDE). A felület atomi szintű tanulmányozásához elektrokémiai pásztázó tűszondás mikroszkóp (STM és AFM) áll rendelkezésünkre. Alkalmazzuk továbbá az elektrokémiai impedancia spektroszkópiát (EIS), uv-látható spektroelektrokémiát és az in situ vezetésmérés módszerét is.
Summary
The main goal of the present project is the preparation and characterization of nanocomposites based on conducting polymers and layered inorganic compounds, as well as their application in the field of electrocatalysis including fuel cells. Lamellar nanocomposites consisting of layered inorganic compounds and conducting polymers display novel properties which result from the molecular interaction of two dissimilar chemical components. We have already demonstrated the intercalative polymerization of aniline and pyrrole in a-RuCl3. Beside RuCl3 other layered compound, e.g., V2O5 will also be investigated. Furthermore, it is intended to prepare nanocomposites by electropolymerization of suitable monomers on different oxides such as TiO2, SiO2 and carbon nanotubes, and polymer-mediator-enzyme and polymer-photochemically active compound composites. The insertion and ionic transport processes will be studied by electrochemical quartz crystal nanobalance (EQCN), the catalytic activity by a rotating ring-disc electrode (RRDE). Scanning probe techniques (electrochemical STM and AFM) will be used to obtain information of the surface at an atomic level. Electrochemical impedance spectroscopy (EIS), UV-VIS spectroelectrochemistry, in situ conductivity measurements will also be used for the characterization of the nanocomposites.




 

Final report

  
Results in Hungarian
Vezető polimerek különböző kompozitjait állítottuk elő. Az új anyagok tulajdonságait különböző módszerekkel, EQCN, RRDE, EIS, AFM and SEM, határoztuk meg. Katalitikus aktivításukat és szuperkapacitás viselkedésüket az általunk tervezett polimer elektrolitos tüzelőanyag-cellákban teszteltük. Az eredményeket a terület vezető folyóirataiban tettük közzé. A hallgatókkal együtt 11 konferencián 24 beszámolót tartottunk. A projektvezető több könyvet és könyvfejezetet publikált a 2008-2012 időszakban. A Vezető polimerek című könyve 2 kiadásban is megjelent, a 2. kiadás részletesen foglalkozik a kompozitokkal is. A kompozitokat hasznosítottuk két, általunk épített járműben (HYGO and HYGO 2.0) is, melyek a Széchenyi futamon elnyerték mind 2009-ben, mind 2010-ben A leginnovatívabb jármű és a Prototípus I. díját, 2009-ben a Honda különdíját is. Az eredeti pályázatban szereplő két doktorandusz (Kriston Á. és Róka A.) fokozatot szerzett. Csorbai Á., Székely A. és Nemes Á. megvédték BSc diplomájukat, Berkes B. vegyészdiplomát szerzett. Továbbra is a témán dolgozik Pröhle Zs. (BSc), Nemes Á. (MSc), Berkes B. (PhD) és Kriston Á (postdoc).
Results in English
Several composites based on conducting polymers have been prepared. The characterization of the new materials has been carried out by EQCN, RRDE, EIS, AFM and SEM techniques. Their catalytic activity and supercapacitor behavior have been tested in polymer membrane fuel cells (PEMFcs) designed and fabricated in the PI's laboratory. The results obtained in the period of 2008-2012 have been published in different leading journals. The project leader with his students have taken part at 11 conferences with 24 presentations. The PI has published several books and book chapters during this period, among others on the Conducting Polymers, Springer (2008 and 2nd edn. 2012, the latter one extended by an extensive discussion on composites). The composites have been utilized in two vehicles (HYGO and HYGO 2.0), which won the prizes (Most Innovative Vehicle, 1st Prize of Prototype in both years as well as the Honda Prize in 2009) at the competition of alternatively driven vehicles called 5th and 6th Szechenyi race in Győr in 2009 and 2010, respectively. The two Ph.D. students, A. Róka and Á. Kriston, have defended their Ph.D. thesis. 3 BSc students (Á. Csorbai, Á. Nemes, A. Székely) and 1 MSc (B. Berkes) defended their diploma work. Zs. Pröhle (BSc), Nemes (MSc), Berkes (PhD) and Kriston (postdoc) still has been working on this project.
