“…The 1365 cm −1 peak represents the secondary amide compounds derived from phenolic plant compounds. The peak at 1218 cm −1 denotes the stretching vibrations of the C-O bond [43][44][45]. The peaks at 898 cm −1 and 516 cm −1 characterised the C-O-Ti-O bonding [46], which recognised the formation of activated carbon-loaded titanium dioxide nanoparticles.…”

Activated carbon doping TiO2 nanoparticles were synthesised by zapota leaf extract using the co-precipitation method. The bio-constituents of plant compounds were used in the reactions of stabilization and reductions. The carbon loading on the TiO2 nanoparticles was characterised by XRD, FTIR, UV-DRS, SEM with EDX, and TEM analysis. The loading of activated carbon onto the TiO2 nanoparticles decreased the crystallite size and optical bandgap, and their doping improved the surface structure of AC/TiO2 nanoparticles. Mesoporous/microporous instability was remodified from the activated carbon, which was visualised using SEM and TEM analysis, respectively. The photocatalytic dye degradation of Rh-B dye was degraded in TiO2 and AC/TiO2 nanoparticles under visible light irradiation. The degradation efficiencies of TiO2 and AC/TiO2 nanoparticles were 73% and 91%, respectively. The bacterial abilities of TiO2 and AC/TiO2 nanoparticles were examined by E. coli and S. aureus. The water reclamation efficiency and bactericidal effect of TiO2 and AC/TiO2 nanoparticles were examined via catalytic dye degradation and bacterial efficiency of activated carbon-doped titanium dioxide nanoparticles.

“…One of the main benefits is the improvement of mechanical, thermal, and optical properties. Research has demonstrated that incorporating TiO2 nanoparticles can greatly enhance the tensile strength, Young's modulus, and toughness of PVA nanocomposites [7]. This enhancement is accredited to the strong interfacial interaction among the NPs and the polymer matrix, resulting in efficient stress transfer and reinforcement.…”

This study investigates the structural, electrical, and optical properties of polyvinyl alcohol (PVA) and Titanium Dioxide(TiO2) NC films. The PVA-TiO2 NC films were prepared using a simple solution casting method, with varying concentrations of TiO2 nanoparticles. The structural analysis revealed the incorporation of TiO2 nanoparticles into the PVA matrix, resulting in a uniform dispersion and improved crystallinity. SEM micrographs demonstrated the uniform dispersion of TiO2 nanoparticles in the PVA matrix. FTIR spectroscopy indicated interaction between TiO2 nanoparticles and the PVA matrix through -OH functional groups. The electrical properties were assessed through DC electrical conductivity studies, which showed an increase in conductivity with increasing TiO2 concentration. The optical properties were characterized using UV-Vis spectroscopy, indicating a significant enhancement in the absorption and transmittance properties of the films with the incorporation of TiO2 nanoparticles. A significant peak of absorption was observed at a wavelength of 225 nm for the nanocomposite films incorporating 8.0 wt.% TiO2 into PVA. The incorporation of 8.0 wt.% TiO2 NPs in PVA polymer led to notable alterations in the direct bandgap, with a decrease from 6.09 eV to 5.28 eV, as well as in the indirect bandgap, with a decrease from 5.53 eV to 4.64 eV. Additionally, the Urbach energy decreased from 0.82 eV to 0.548 eV. Among the samples, the one with 8.0 wt.% TiO2 exhibited the highest DC electrical conductivity at 338 K, measuring 5.59x10−13 Scm−1, and at 393 K, measuring 4.01x10−8 Scm−1. The PVA-TiO2 NC films exhibited excellent potential for applications in optoelectronic devices due to their enhanced electrical and optical properties. UV-Vis spectroscopic studies revealed that these nanocomposites can be utilized in UV-shielding and optoelectronics devices. There is significant room for further study of these materials for potential applications.
