Final report

 
Results in Hungarian
A Ni-Fe-LDH eseteben a katalitikus aktivitás az enyhen torzult oktaéderes szerkezetnek köszönhető, amelyben az aktív szpeciesz a vas. A kutatas soran kulonbozo osszetetelu, vas tartalmu katalizatorokat allitottam elo, hagyomanyos egyuttlecsapassal es szen papirra elektrokemiai uton is. Az igy eloallitott katalizatorokat jellemeztuk, tobbek kozott AP-XPS es in situ XAS vizsgalatokkal is. Autochem es DRIFT dinamikus meresekkel kapott eredmenyekbol pedig kovetkeztetni lehet a feluleti savassagra, illetve a Fe elektrokatalitikus aktivitasban betoltott szerepere.
Results in English
Ni Fe double oxide hydroxides are among the most efficient earth-abundant catalysts for the oxygen evolution reaction (OER) under alkaline conditions. One of the possible reason for the Ni-Fe-LDH`s catalytic activity is the distorted octahedral structure, where the active sites are related to the iron. The role of the different types of structural water and/or their coordination environments in the OER is currently unknown. In the present work, our goal was to investigate the effects fine structure of a series of M(II) Fe(III) LDHs, where M(II) is Cu(II) , Co(II) , Fe(II) , Ca(II) , Ni(II) and Mg(II). Beside many others AP XPS and in situ XAS measurements were applied to reveal the correlation of the structure and the electrocatalytic activity of certain compounds.
