Synthesis of metal-organic frameworks

Metalo-organske mreže (MOF) su posebni materijali koji su savršena poveznica anorganske i organske kemije. Građeni su od centralnog atoma koji je anorganski metal, te organskog liganda. MO mreže tvore novu vrstu poroznih materijala jer se razlikuju zbog svoje velike površine i pora, male gustoće, te velike stabilnosti i funkcionalnosti. Velika primjena metaloorganskih mreža je u petrokemijskoj industriji, biomedicini, katalizama, itd. Sinteza novih metalo-organskih mreža uvelike pospješuje očuvanju ekologije i okoliša budući da se u ovisnosti o veličini pora koriste za skladištenje štetnih plinova i zagađivača u okolišu. Cilj ovog rada bio je sintetizirati metalo-organsku mrežu koristeći heksametilentetraamin kao templat pri sobnoj temperaturi. Korišteni su različiti metali poput Co, Mn i Cr s propanskom kiselinom kao ligandom.Metal-organic framework is a special family of compounds which represents the perfect link between inorganic and organic chemistry. They are made up of a central metal cation and an organic ligand. MO frameworks form a new type of porous material because they have a large surface area and large pores, low density, high stability and functionality. Great applications of metal-organic frameworks are found in petrochemical industry, biomedicine, catalysis, etc. The synthesis of novel metal-organic frameworks greatly contributes to ecology and the preservation of the environment because depending on a pore size, various harmful gases and pollutants can be stored within the pores. In this research, the aim was to synthesize metal-organic frameworks using hexamethylenetetraamine as a template at room temperature. Various metals as Mn, Co and Cr were used in combination with propionic acid as the ligand
