Summary: An amorphous TiO2 nanoparticle (8-AT) was prepared via sol-gel method with pH adjustment to 8 using ammonia. The 8-AT had a particle size of 20-24 nm and specific surface area of 365.68 m2/g. It showed higher degradation efficiency for tetracycline (TC) compared to anatase TiO2 and P25, achieving 93.9% degradation within 30 minutes in dark reaction and 60 minutes under visible light irradiation. The study proposed a possible degradation mechanism based on the adsorption-photocatalytic activity of 8-AT.

Summary: A sol-gel method was used to synthesize Mn-doped TiO2 nanoparticles with different concentrations. The synthesized nanoparticles were characterized using XRD, XPS, TEM, and DRS. The results showed that Mn doping affected the phase composition, oxidation states of Mn, and morphology of the nanoparticles. The Mn-doped TiO2 0.2wt.% sample exhibited the highest photocatalytic activity for MB degradation and E. coli photokilling under visible light irradiation.

Summary: Nanosized lanthanum titanate synthesized by a glycine-assisted sol gel route shows improved photocatalytic properties. The optimum calcination temperature of 1000 degrees C results in the best efficiency. The photocatalyst exhibits higher degradation rate of rhodamine B compared to commercial P25 TiO2 and sol-gel synthesis without glycine. Photodegradation of phenol also demonstrates the effectiveness of the photocatalyst with a high apparent rate constant.

Summary: The Sb-doped SnO2-SiO2 film shows reduced crystallinity with Sb doping, exhibiting M-shaped changes in lattice parameters with increasing Sb concentration. Nanoparticle size decreases and then increases with Sb doping levels above 6 mol%. Additionally, the transmittance of the glass substrate coated with this film decreases, while resistance and dust removal performance exhibit complex changes with varying Sb concentrations. At 12 mol% Sb doping, the film exhibits minimal resistance and a 64% dust removal performance.

Summary: The rise of antibiotic waste in water has become a pressing issue for both human health and the environment. In this study, a sol-gel amalgamation of nanocrystalline La-doped NaTaO3 perovskites modified with Bi2O3 showed promising results in photocatalytic degradation of the emergent antibiotic ciprofloxacin. The close junction of Bi2O3 and NaTaO3 contributed to improved photoinduced charge transfer and energy bandgap suppression, leading to efficient removal of antibiotics through visible-light irradiation.

Summary: NiOx, Li:NiOx, and Li,Mg:NiOx powders were produced by sol-gel method, and their structural and optical properties were studied. XPS results confirmed the successful incorporation of Li+ and Mg2+ into NiOx structure, with decreased crystallite size as dopant concentration increased. Addition of Li+ and Mg2+ led to reduced emission intensity and average decay time compared to pristine NiOx.
