Summary: The organic-inorganic polyaniline (PANI)/ZnO nanocomposite was synthesized with different weight percentages of ZnO, and the PANI/ZnO (10 wt%) composition showed excellent conductivity and maximum photocatalytic activity for the degradation of methylene blue under natural sunlight. The synergistic interaction between PANI and ZnO, as well as high photogenerated charge carrier separation, are believed to contribute to the superior performance of PANI/ZnO (10 wt%) nanocomposites.

Summary: Photocatalytic degradation of dyes using metal oxides and their composites is an effective method for removing pollutants from wastewater systems. The coupling of metal oxides increases the efficiency of the process, thanks to their ability to absorb broad spectrum light, operate quickly, and exhibit natural p-n characteristics. In this study, binary and ternary nanocomposites of Copper Oxide/Zinc Oxide (CuO/ZnO) and beta cyclodextrin (beta-CD) were prepared using the sol-gel method. The synthesized materials were characterized using various techniques, and their photocatalytic performance was tested using model textile dyes. The addition of beta-CD improved the efficiency of the catalyst and reduced electron hole recombination. The beta-CD-CuO/ZnO nanocomposite exhibited superior photocatalytic activity compared to CuO/ZnO, with degradation efficiencies of up to 89.15% and 79.90% for MB and MG dyes, respectively, after 180 minutes of irradiation.

Summary: Removing organic pollutants, textile dyes, and pharmaceutical wastes from water bodies is crucial for a safe environment. This study developed semiconductor zinc oxide nanoparticles (ZnO NPs) and plasmonic Ag-supported ZnO nanocomposites (ZnO-Ag) using a bio-approach as an alternative to hazardous synthesis methods. The ZnO-Ag nanocomposite exhibited enhanced photocatalytic activity for the degradation of methylene blue (MB) dye due to the presence of plasmonic Ag NPs and the surface plasmon resonance (SPR) effect. The research provides valuable insights for the future application of noble metal-modified nanocatalysts in water treatment.

Summary: Polyaniline (PANI) and multi-walled carbon nanotubes (MWCNTs) were incorporated into hollow CdS spheres to create CdS/PANI/MWCNTs nanocomposites. These nanocomposites were utilized as photo-catalysts for the degradation of sodium butyl xanthate (SBX) in wastewater. The optimized CdS/PANI/MWCNTs catalyst exhibited excellent ultraviolet-light-driven photocatalytic performance with a degradation rate of 99.2% in 70 minutes. The enhanced catalytic activity was attributed to the facilitated separation of photogenerated electrons and holes by PANI, as well as the promotion of SBX adsorption and electron migration by MWCNTs. The stability of CdS/PANI/MWCNTs was also demonstrated by the inhibited photocorrosion of CdS.

Summary: The present study successfully synthesized highly porous TiO2 by incorporating PANI polymer into the sol-gel chemistry of TiO2/TTIP. The TP samples exhibited a porous ginger-like nanostructure with smaller particle size compared to pristine TiO2. XPS analysis confirmed the presence of hydrogen bonds between Ti-OH groups of TiO2 and protonated nitrogen of PANI. UV-visible absorption study showed a small shift in absorption wavelength for TP8 sample and a reduction in Eg value. FTIR results confirmed the interaction between PANI and TiO2. The TP8 sample showed high photocatalytic activity towards Methylene blue dye degradation. The study offers an excellent photocatalyst TP8 with 8 wt% of PANI for the degradation of MB dye. Evaluation: 8 points
