AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules. Considering that the photocatalytic activity of the cotton-based TiO2 and TiO2/Ag samples was practically imperceptible, it can be assumed that the synthesized Ag NPs act predominantly as electron traps in the double-loaded synthesized system.

objective of this research paper is to ensure understanding of the influence of size,
shape, structure and doping level on optical and magnetic properties of TiO2
 nanoparticles, as well as the interaction between nanoparticles and PANI due to the
creation of desired photocatalytic properties of nanocomposites.
The doping of TiO2

HJ

transitions of Sm3+ in the 4f5
 configuration, after band-to-band excitation, confirming the accomplishment of energy transfers.
The Ni2+ doped TiO2
 nanocrystals enabled the synthesis of optically transparent nanostructured films that showed room-temperature ferromagnetism with
almost closed loop (HC ~ 150-200 Oe) and saturation magnetization in the range of
10-3-5x10-2 μB/Ni depending on dopant concentration. Ni2+ ions that substitute core
Ti atoms were found to participate in the light excitation processes, too.
The improvement of photocatalytic efficiency of TiO2
 nanocrystals by surface modification with carbonized form of PANI was tested in degradation processes of Rhodamine B and Methylene blue. The carbonized PANI/TiO2
 nanocomposites showed significantly higher photocatalytic efficacy compared to the bare TiO2
and the non-carbonized PANI/TiO2
 nanocomposites. Their photocatalytic activity
is influenced by their surface and crystalline structures, absorption coefficient in
the visible part of the spectrum, high mobility of charge carriers and finally by the
molecular structures of the organic dyes used.
