Summary: The hydrothermal method was used to synthesize TiO2 nanoparticles and TiO2/La2O3, TiO2/Al2O3 composites. The crystal structure, shape, and optical characteristics were studied using FTIR spectroscopy, XRD, UV-Vis absorption spectroscopy, and SEM. Photocatalytic properties were evaluated by degrading methylene blue (MB) and crystal violet (CV) dyes under UV and visible light. TiO2/La2O3 exhibited the highest photocatalytic efficiency, while TiO2/Al2O3 showed the lowest efficiency.

Summary: Producing freshwater from seawater and wastewater is important, and a three-dimensional carbonized pine cone (CPC1) was fabricated as a low-cost and efficient photoabsorber for this purpose. CPC1 exhibited high conversion efficiency and evaporation flux due to its large solar-light-harvesting ability, porosity, rapid water transportation, water/air interface, and low thermal conductivity. It also showed good stability and the ability to purify seawater and wastewater through the removal of organic dyes and reduction of polluting ions.
