Summary: TiO2 nanowires were synthesized by hydrothermal method and calcined at different temperatures. The samples were characterized using X-ray diffractometry (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photocatalytic efficiency of TiO2 was evaluated by the degradation of Rhodamine B (RhB). The study revealed the formation mechanism of TiO2 nanowires. The results indicated that the calcination temperature significantly influenced the crystal structure and morphology of TiO2 nanowires. The TiO2 sample calcined at 650°C exhibited higher photocatalytic activity due to its enhanced crystallinity and nanowire structure with a large specific surface area.

Summary: TiO2/BiOI photocatalysts with microsphere morphology were synthesized by a solvothermal method. Among them, (001)-TiO2/BiOI showed the highest photocatalytic performance, with a RhB degradation rate of 0.049 min(-1) under visible light, which is 5 and 7 times higher than that of (001)-TiO2 and BiOI, respectively. This improvement in photocatalytic efficiency can be attributed to the formation of heterojunctions, which enhance the transportation of photo-generated carriers. The prepared photocatalysts demonstrated good photochemical stability through cycling experiments, and O-2(-) and OH were identified as the principal active species in the photocatalytic reaction mechanism. Additionally, a possible mechanism of p-n heterojunctions in the photocatalytic reaction process was proposed.
