Abstract:Magnetni nanodelci (MND) so že dosegli široko uporabo v biomedicinskih aplikacijah, diagnostiki, mehaniki, katalizi in sanaciji okolja. Napredek v razvoju tehnologije je omogočil združitev MND z drugimi materiali, kar imenujemo nanokompozit. Nanokompozit je material, ki ima dimenzije manjše od 100 nm, ter izraža združene lastnosti mešanih materialov. V diplomski nalogi smo sintetizirali magnetno-zeolitni nanokompozit, material, ki združuje lastnosti zeolitov in MND. MND smo sintetizirali z metodo koprecipitacije oz. s soobarjalno metodo. Zeolita 4A in 13X smo mleli v planetarnem krogličnem mlinu v različnih masnih razmerjih in pri različnih časih. S spreminjanjem parametrov smo ugotavljali, katera kombinacija parametrov poda najboljše rezultate za sintezo magnetno-zeolitnega nanokompozita. Z mletjem smo želeli dobiti čim večjo površino zeolita, saj ima takrat največ aktivnih mest, na katera se bodo vezali MND. Vzorce smo analizirali s termogravimetrično metodo (TGA), dinamičnim sipanjem svetlobe (DLS), infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR) in Brauner-Emmett-Tellerjevo metodo (BET).

Title:The influence of milling parameters on zeolite properties and the synthesis of magnetic-zeolite nanocomposites
Abstract:Magnetic nanoparticles (MNPs) have already achieved widespread use in biomedical applications, diagnostics, mechanics, catalysis and environmental remediation. Advances in technology have enabled the combination of MNPs with other materials, resulting in what is known as a nanocomposite. A nanocomposite is a material with dimensions smaller than 100 nm and exhibits the combined properties of constituent materials. In our thesis, we synthesized a magnetic-zeolite nanocomposite, a material with the properties of zeolites and MNPs. MNPs were synthesized using the coprecipitation method. Zeolites 4A and 13X were ground in a planetary ball mill using different mass ratios and grinding times. By changing the parameters, we determined which combination yields the best results for synthesizing the magnetic-zeolite nanocomposite. The goal of grinding was to obtain the largest possible surface area of zeolite, as this provides the most active sites for MNP binding. The samples were characterized with thermogravimetric analysis (TGA), dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR) and Brauner-Emmett-Teller (BET) method.
