Summary: Undoped barium oxide and neodymium-doped barium oxide nanoparticles were synthesized using the co-precipitation technique. The synthesized nanoparticles were found to have a cubic structure, and their properties such as crystallite size, morphology, and composition were characterized. The neodymium-doped barium oxide showed a lower band gap energy and activation energy compared to the undoped barium oxide. Additionally, it exhibited higher efficiency in photocatalytic degradation of dyes.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.

Summary: High quality silver (Ag) decorated CeO2 nanoparticles were prepared by a facile one-step chemical method and used as a catalyst for degrading harmful textile pollutant Rose Bengal dye under sunlight with a high efficiency of 96% degradation rate after 3 hours. The enhancement in degradation efficiency was mainly attributed to the decrease in band gap and charge carrier recombination rate, with a possible degradation mechanism proposed based on the generation of oxygen vacancies due to the decoration of Ag on the CeO2 surface.

Summary: An eco-friendly synthesis of silver nanoparticles (SNPs) was optimized using Teucrium stocksianum extract and compared to fresh and air-dried plant extracts. The biosynthesized SNPs exhibited significant antimicrobial activity at low concentrations and were more effective than the parent plant extract. The biosynthesized SNPs also showed efficient photolytic degradation of methylene blue under sunlight.

Summary: Ag/AgCl and Au BNPs were synthesized using Azadirachta indica leaf extract, and their specific surface plasmon resonance was characterized. The BNPs exhibited core-shell and alloy structures, with a crystalline nature and a particle size in the range of 5.68 nm to 13.25 nm. Among them, only Ag/AgCl-Au BNPs (alloy) showed antibacterial activity. The influence of physicochemical parameters on the degradation of Rh-B and MO dyes in the presence of SBH was investigated, with Ag/AgCl-Au BNPs (alloy) showing the highest degradation efficiency.
