Summary in Hungarian
A jelen projekt fő célja vezető polimer alapú kompozit és hibrid anyagokban lejátszódó folyamatok mibenlétének megértése. Úgy gondoljuk, hogy az eredmények alapján nagy energiáju és teljesítményű szuperkapacitások, hatásos elektronvezető katalizátorrétegek tervezhetők, amelyek azután felhasználhatóak lesznek tüzelőanyag-cellákban illetve ezekkel kombinálva. A töltési-kisütési folyamatok során végbemenő szerkezeti és koncentrációváltozásokat elektrokémiai kvarckristály-nanomérleg segítségével kívánjuk követni. A katalitikus aktívitást forgó gyűrűs korongelektródokkal vizsgáljuk. Pásztázó mikroszkópos technikák (elektrokémiai STM és AFM) segítségével az atomi szintű felületi változásokat fogjuk tanulmányozni. Elektrokémiai impedanciaspektroszkópia és ultraibolya-látható spektroelektrokémiai mérések teszik teljessé vizsgálati eszköztárunkat. Amint azt már korábban bizonyítottuk anilin és pirrol interkalatív polimerizációjával RuCl3 és RuO2 rétegekben hatékony, stabilis és változtatható tulajdonságú szuperkapacitások és katalizátorok hozhatók létre. E rendszerek tulajdonságainak javítása céljából olyan polimereket állítunk elő, amelyeken különböző funkciós csoportok vannak, pl. flourozott vagy szulfonált polianilint, politioféneket, valamint kopolimerjeiket és ezek Ru- és ftalocianinvegyületekkel, illetve szén nanocsövekkel, kubánvegyületekkel illetve pórusos szénnel készült kompozitjait kivánjuk vizsgálni. Korábban kimutattuk, hogy a platina katalizátor szokatlan viselkedést mutat Pt-Nafion-szén rendszerekben; e jelenségek alaposabb megértése céljából további vizsgálatokat szükséges folytatnunk. Az oxigénredukció gátolt volta még mindig a legnagyobb probléma jó teljesítményű tüzelőanyag-cellák létrehozásában. Ezért kutatásunk fontos része irányul annak vizsgálatára, hogy e folyamat sebességét növeljük, hozzá még oly módon, hogy egyidejüleg csökkenteni tudjuk a katalizátorréteg nemesfém tartalmát is. A szuperkapacitásokban a Ru felváltása olcsóbb, de ugyanolyan hatékony és stabilis anyagokkal szintén e projekt célja.
Summary
The proposed research is aimed at the understanding the basic phenomena in composite and hybrid materials based on conducting polymers. We believe that the results obtained will create a solid fundamental basis for designing high energy and power density supercapacitors, high-performance electroconducting catalyst layers applied in and in combination with fuel cells. The electrochemical quartz crystal nanobalance (EQCN) technique may serve as a gravimetric probe of the compositional and concentration changes in these materials during their charging-discharging processes. The catalytic activity will be investigated by rotating ring-disc electrodes. Scanning probe techniques (electrochemical STM and AFM) will be used to obtain information on the surface at an atomic level. Electrochemical impedance spectroscopy, UV-VIS spectroelectrochemical methods will also be applied. We have already demonstrated that by intercalative polymerization of aniline and pyrrole in RuCl3 and RuO2 very effective, stable and tunable supercapacitors and catalysts can be obtained. In order to improve the performance of these systems functionalized polymers such as flourinated, sulfonated polyanilines, polythiophenes and copolymers will be prepared and applied in combinations of Ru- and phtalocyanine compounds as well as carbon nanotubes, cubanes and nanoporous carbons. Based on our previous achievements concerning the unusual behavior of platinum catalyst in Pt-Nafion-carbon systems further studies are planned to gain a deeper understanding the phenomena occurring in these composites.
The oxygen reduction is still the limiting step in fuel cells. Therefore, this process will be studied in detail in order to increase its rate, and simultaneously to decrease the amount of the noble metals needed. The replacement of Ru in supercapacitors is also one of the goals of this project.




 

Final report

  
Results in Hungarian
Az eredeti tervnek megfelelően a következő kompozit és hibrid rendszereket vizsgáltuk: Fe-ftalocianin, Pd-ftalocianin, poly (réz-ftalocianin) és többfalú szén nanocsövek, elektronvezető polimerek illetve protonvezető Nafion. A rétegképződést és az ioncserefolyamatokat elektrokémiai kvarckristály nanomérleggel, míg az oxigénredukciót forgó korongelektróddal vizsgáltuk tág határok között változtatva a kísérleti körülményeket. Sikeresen polimerizáltuk az indolt illetve annak amino származékait. Az elektropolimerizáció körülményeit optimalizáltuk; a különböző korszerű technikákkal való vizsgálat kimutatta, hogy ez az új, olcsó alapanyagból előállított polimer számos kedvező kémiai, elektromos és stabilitási tulajdonsággal rendelkezik. Az alapkutatási eredményeket tudományos folyóiratokban publikáltuk illetve a témavezető és a projekten dolgozó egyetemi hallgatók és doktoranduszok nemzetközi konferenciákon mutatták be az eredményeket. Ezen időszakban Szabó Franciska, Broda Balázs BSc, Colin E. Moore és Borsos Katalin MSc valamint Kriston Ákos, Berkes B. Balázs és Nemes Ákos PhD hallgatók dolgoztak a projekt különböző témáin. A fém-ftalocianin alapú kompozitok hasznosítása oxigénredukció katalizátoraként folyamatban van, különösen hidrogén-oxigén tüzelőanyag-cellákban. Igazoltuk, hogy ezekkel a rendszerekkel hatásosan kiváltható a drága platina. Ugyancsak bízonyítást nyert, hogy a vezető polimerek és a szén nanocsövek kompozitjai hatásosan felhasználhatók szuperkapacitásokban.
Results in English
According to our original research plan we have continued the research on the composite and hydrid systems as follows: Fe-phthalocyanine, Pd-phthalocyanine, poly (copper phthalocyanine) with multi-walled carbon nanotubes, electronically conducting polymers and Nafion. The layer deposition and the ion exchange processes have been investigated by electrochemical quartz crystal nanobalance (EQCN), their electrocatalytic activity in respect of the oxygen reduction was studied by rotating ring electrode at different experimental conditions. Successful experiments have been carried out on the electropolymerization of indole and several indole derivatives. The conditions of the electropolymerization have been optimized, and the resulting polymers have been characterized by several advanced techniques. The results of these fundamental studies have been published in scientific journals and presented at international conferences by the PI and his students, respectively. In the period in question B. Broda (BSc), C. E. Moore, K. Borsos (MSc) and Á. Kriston, B.B. Berkes, Á. Nemes (PhD) worked in the project. The utilization of the metal-phthalocyanine composites are in progress concerning oxygen reduction reaction in hydrogen-oxygen fuel cells. It has become evident that expensive platinum can be replaced by these cheap systems. It has been proven that the composites based on conducting polymers and carbon nanotubes can be used as effective and stable systems in supercapacitors.
