چکیده انگلیسی
Two different nanoclay minerals were combined with nanophase anatase TiO2 for the synthesis of clay-based nanocomposites for improved photocatalytic properties. A new Halloysite (Hal) + Sepiolite (S) - TiO2 ternary nanocomposite was prepared using halloysite from Utah, USA and a recently discovered sepiolite from Greece. Three nanocomposites were synthesized with Hal-TiO2, S-TiO2 and [Hal+S] to TiO2. As a result, TiO2 particles (anatase) were homogeneously deposited and dispersed on the clay surfaces. Phase composition, particle morphology and physical properties of these nanocomposites were characterized by XRD, ATR-FTIR, FE-SEM, DRS-UV-Vis and N2-sorption/desorption isotherms at 77â¯K. The photocatalytic activity of the clay mineral-TiO2 nanocomposites was examined in the decomposition of paracetamol and tetracycline antibiotics as well as dye Rhodamine-B. The nanocomposites exhibited higher photocatalytic activity under UV irradiation for the decomposition of the targeted pollutants than the benchmark in the field, i.e. TiO2- P25 photocatalyst.
