    Dizajn novih heterogenih katalizatora za obnovljivu energiju temeljen na metalnim kvantnim klasterima i okru\u017eenju<\/strong><\/p>\n\n\n\n

    SA\u017dETAK<\/strong>:<\/p>\n\n\n\n

    Teza isti\u010de prednosti sustavnog uklju\u010divanja metalnih kvantnih klastera unutar razli\u010ditih okru\u017eenja s ciljem dizajniranja novih klasa heterogenih katalizatora. U tom kontekstu, fokus je na novim odr\u017eivim rje\u0161enjima za pobolj\u0161anje performansi gorivih \u010dlanaka kroz materijale za proizvodnju i skladi\u0161tenje vodika te eliminaciju i kori\u0161tenje ugljikovog monoksida. Tako\u0111er, predla\u017eu se kataliti\u010dki sustavi za efikasnu i selektivnu pretvorbu ugljikovog dioksida u korisne produkte. Teorija funkcionala gusto\u0107e (DFT) koristi se za predvi\u0111anje novih katalizatora kroz istra\u017eivanje \u0161irokog spektra sustava kako bi se dobio uvid u prirodu aktivnih mjesta i ulogu okru\u017eenja. Ovo se posti\u017ee kroz istra\u017eivanje strukturalnih i elektronskih svojstava katalizatora kao i kroz odre\u0111ivanje energijski povoljnih puteva koji vode do \u017eeljenih produkata. Strategije dizajna novih materijala temelje se na i) integraciji metalnog bakrenog centra unutar metalo-organske mre\u017ee i za\u0161titi klastera srebrovog hidrida pomo\u0107u liganada, ii) prijenosu ligandiranog rutenijevog klastera unutar zeolita te iii) odlaganju monometalnih i bimetalnih bakrenih klastera dopiranih paladijem na povr\u0161inu metalnog oksida. Teorijski rezultati nadopunjeni su eksperimentalnim rezultatima na\u0161ih suradnika te omogu\u0107uju fundamentalno razumijevanje i kontrolu funkcije novih katalizatora.<\/p>\n\n\n\n

    Title:<\/p>\n\n\n\n

    Design of new heterogeneous catalysts for renewable energy based on metallic quantum clusters and the surrounding<\/strong><\/p>\n\n\n\n

    ABSTRACT<\/strong>:<\/p>\n\n\n\n

    The thesis highlights the potential of metallic quantum clusters placed in various surroundings in the design of new classes of heterogeneous catalysts. In this context, new sustainable solutions are addressed through the design of materials for enhancement of fuel cell performance via production and storage of hydrogen as well as the elimination and utilization of carbon monoxide. In addition, catalytic systems for carbon dioxide conversion into useful products are proposed. Density functional theory (DFT) is used to predict the new catalysts by exploring a wide range of systems, providing an insight into the nature of active sites and the role of the surroundings. This is achieved through investigations of structural and electronic properties of the catalysts, as well as energetically favorable pathways leading to the desired products. The strategies for new material design are based on i) integration of a copper-based metallic center within the metalorganic framework and ligand protection of silver hydride cluster, ii) placing ligated ruthenium cluster inside the zeolite, and iii) depositing of monometallic and palladium-doped bimetallic copper clusters on metal oxide support. The results emerging from theoretical calculations are supplemented by experimental results obtained by our collaborators, enabling fundamental understanding and control of the function of new catalysts.<\/p>\n","protected":false},"excerpt":{"rendered":"
