Summary: The photocatalytic degradation of low-density polyethylene (PE) films with titanium and manganese dioxide nanoparticles was investigated. Composite PE films with different photocatalysts were prepared and subjected to UV irradiation. Tests and measurements on the PE films were conducted to evaluate the effects of the nanoparticles on the degradation and thermal behavior of PE. The results showed the coupling effects of titanium and manganese dioxide nanoparticles on PE degradation, and the influence of the nanoparticles on the tensile properties and wettability of the films.

Summary: In this study, the adsorption and photocatalytic degradation of oxytetracycline (OTC) were investigated using different metal-doped TiO2 nanocatalysts (M-TiO2, M = Fe, Co, Ni, Cr). The effects of different metal dopants on the adsorption and degradation abilities of TiO2 were studied. The photocatalytic performance of Fe-TiO2 was found to be excellent due to the synergy between the separation ability of photogenerated carriers and the adsorption ability of pollutants.

Summary: The Cu/TiO2/FA composite was optimized for the removal of the model dye pollutant methyl orange under visible light irradiation using response surface methodology and Box-Behnken experimental design. The study considered three independent variables and achieved a 99.91% removal rate under the optimal operating conditions. The results support the hypothesis of a combined and synergic adsorption-photocatalytic degradation process for pollutant removal.

Summary: This study focuses on the synthesis of TiO2/CdS nanocomposites with different concentrations of precursors and their characterization using various techniques. The results show that TiO2/CdS nanocomposites exhibit excellent photocatalytic performance in the visible range compared to pure TiO2, and they have better degradation efficiency for methylene blue dye compared to rhodamine B dye. The optimum photocatalytic performance is achieved with a 1:1 M ratio of cadmium and sulphur precursors.

Summary: The photocatalytic activity of zirconia thin films fabricated by a sol-gel method was studied under UV-C irradiation, with those annealed at 500-700 degrees Celsius showing higher activity compared to those annealed above 800 degrees Celsius. This suggests that pure ZrO2 with wide bandgap energy is a promising candidate for photocatalysis under UV-C irradiation.
