Summary: In this study, a V2O5 nanorods/GO nanocomposite was synthesized and used as an efficient photocatalyst for the degradation of VB dye under direct sunlight illumination, achieving almost complete degradation within 90 minutes. The excellent photocatalytic efficiency was attributed to the outstanding transfer of interfacial charge and the suppression of charge-carrier recombination. Kinetics of the degradation process was analyzed by calculating rate constants and half-life times, and a possible mechanism for the degradation process was discussed.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
