Abstract	Catalyticreactivity of the small transition and coinage metal nanoclusters have been theoretically studied in context of (1) advancing fuel cell technology by developing cost-effective techniques to improve quality of the feed gas as well as (2) safe storage and release of hydrogen in its gaseous state at room temperatures and pressures. In order to address the challenge concerning the improvement the quality of fuel cell feed gas reactions of small ruthenium cationic nanoclusters with CO and H2 has been performed. The origin of the selectivity and outstanding activity of small ruthenium nanoparticles in the catalytic CO methanation reaction has been identified. The second aim of this dissertation is to advance materials for hydrogen storage and their release technology. For this purpose a gas-phase study of fragmentation and catalytic activity of ligated coinage metal hydride nanoclusters has been performed. The theoretical findings based on density functional theory (DFT) are strongly supported by experimental results trough international cooperation. Within thesis we demonstrated that powerful combination of density functional theory and experimental investigations can contribute to intelligently developed new materials and procedures to overcome the challenges hampering worldwide application of fuel cells as ”green” technology of the future.
Abstract (croatian)	Katalitička reaktivnost malih nanoklastera prijelaznih metala teorijski je istraživana u kontekstu (1) unaprjeđenja tehnologije gorivnih članaka razvijajući jeftine tehnike poboljšanja kvalitete pogonskog plina kao i (2) sigurne pohrane i otpuštanja vodika u plinovitom stanju na atmosferskoj temperaturi i tlaku. Da bi riješili problem nedovoljne kvalitete pogonskog plina gorivnih članaka istraživale su se reakcije malih rutenijevih nanoklastera s CO i H2 . Izvor selektivnosti i izvrsne aktivnosti malih rutenijevih čestica u katalitičkoj CO metanacijskoj reakciji je identificiran. Drugi cilj ove disertacije ja unaprjeđivanje materijala za tehnologiju pohrane i otpuštanja vodika. U tu svrhu provela su se istraživanja fragmentacije i katalitičke aktivnosti ligandiranih metalnih hidridnih nanoklastera. Naša teorijska istraživanja bazirana na teoriji funkcionala gustoće su potvrđena eksperimentalnim rezultatima priznatih istraživačkih grupa kroz međunarodnu suradnju. Unutar ove teze demonstrirali smo da moćna kombinacija našeg teorijskog istraživanja potvrđena eksperimentalnim istraživanjima može doprinijeti inteligentnom razvoju novih materijala i procedura da bi se nadišli problemi koji sprječavaju široku primjenu gorivnih ćelija kao ”zelene” tehnologije budućnosti.
