Synthesis of Polyaniline Supported CdS/CdS-ZnS/CdS-TiO2 Nanocomposite for Efficient Photocatalytic Applications

Nida Qutub et al.

Summary: Photocatalytic degradation can be enhanced by improving photo-generated electrons and expanding the absorption range of light through conductive polymers. In this study, Polyaniline (PANI) was synthesized with CdS, CdS-ZnS, and CdS-TiO2 nanocomposites and evaluated for the degradation of Acid blue-29 dye. The performance of composite photocatalysts was enhanced by PANI, and the properties of the nanocomposites, including charge transfer, molar ratio, surface morphology, particle size, thermal stability, and optical properties, were characterized. The photocatalytic activity and degradation rate were found to increase with the number of nanocomposites in the membranes. CdS-ZnS-PANI and CdS-TiO2-PANI nanocomposites showed higher photocatalytic activity compared to CdS-PANI due to the improved electron kinetics and reduced charge recombination. The efficiency of the photocatalysts remained stable after repeated use, indicating their potential use for water purification. The compatibility between CdS and Zinc and TiO2, along with improved charge carrier separation, contributed to the higher photocatalytic activity of CZP and CTP photocatalytic membranes compared to CdS-PANI. The study also demonstrated the commercial utility of the nanocomposites, as they were active in the near-ultraviolet to deep infrared range and exhibited enhanced stability and reusability. Therefore, the development of high-performance photocatalysts using conductive polymers and nanocomposites holds great potential for environmental purification and solar power conversion.

Modifications in structural, morphological and optical properties of TiO2 nanoparticles: effect of pH

Shweta Manchwari et al.

Summary: Titanium dioxide (TiO2) is a unique system for studying nanoscale phenomena due to its optical and electrical properties. This study synthesized three different samples of TiO2 using different acidic concentrations, and compared their properties. Hydrothermal synthesis was used to produce TiO2 nanoparticles, and the acidic concentration was controlled using nitric acid (HNO3). Characterization techniques were used to study the structural, morphological, and optical properties of the nanoparticles. The results showed that the acidic concentration affected the size, morphology, and band gap energy of the TiO2 nanoparticles.

Synthesis of N-Doped TiO2 for Efficient Photocatalytic Degradation of Atmospheric NOx

Tamal Tahsin Khan et al.

Summary: Titanium oxide (TiO2) is a potential photocatalyst for removing toxic NOx from the atmosphere, but its low absorption of visible light and high charge recombination limit its practical application. Nitrogen-doped TiO2 (TC) shows enhanced visible-light absorption and improved separation/transfer of photo-excited charge carriers, leading to excellent photocatalytic activities in NO oxidation under UV and visible light irradiation.

Effect of synthesis method parameters on properties and photoelectrocatalytic activity under solar irradiation of TiO2 nanotubes decorated with CdS quantum dots

Aleksandra Pieczynska et al.

Summary: Experimental results showed that CdS-Ti/TiO2 nanocomposites exhibited more than twice higher photocatalytic and PEC IF degradation efficiency under UV-Vis irradiation compared to pristine Ti/TiO2. The presence of CdS quantum dots led to a greater contribution of h(+) and generation of other oxidants, enhancing the PEC activity of the nanocomposites.
