This dissertation is dedicated to the synthesis and investigation of the properties and catalytic application of pillared clays based on smectite rich bentonite material from Bogovina mines in Serbia. The obtained pillared clays were tested as catalysts in catalytic and electrocatalytic oxidation of organic water pollutants. The fraction of particles with diameters smaller than 2 μm, richer in smectite, was obtained by hydroseparation. It was referred to as PU. PU was submitted to Na-exchange procedure, resulting in Na-enriched material denoted NaIz, followed by pillaring with Al or mixed Al,Fe, Al,Cu and Al,Co polyhydroxi cations. A series of Al,Fe modified samples was obtained using pillaring solutions with the following 100Fe3+/Al3+ ratios: 1, 5, 10, 15 and 20%. The obtained materials were denoted AlFe1M, AlFe5M, AlFe10M, AlFe15M and AlFe20M. Corresponding ratio in AlCu and AlCo modified samples was 10% and they were denoted AlCu10M and AlCo10M. Phase and chemical composition, chemi...cal structure, textural and morphological properties of PU, NaIz and PILC samples were determined by XRPD analysis, ICP-OES spectrometry, N2 adsorption-desorption method and SEM microscopy. AlFe PILCs were additionally analyzed by FTIR spectrometry, DRUV-Vis spectrophotometry and Mössbauer spectrometry...
