Facile synthesis of metastable CaTi2O5 nanostructure and its photocatalytic properties
Source abstract
Abstract
Abstract Metastable CaTi2O5 nano-structure has been selectively prepared by a template-free and surfactant-free solvothermal process in aqueous solution. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) are carried out to characterize the samples. The growth process for CaTi2O5 shuttle-like structure was dominated by a crystallization – oriented attachment – Ostwald ripening growth mechanism. BET analysis shows that CaTi2O5 shuttle-like structure owns a large surface area of 118.8 m2 g−1. Compared with the other samples synthesized at various time and P25, CaTi2O5 shuttle-like structure synthesized at 36 h exhibits the highest photocatalytic activity. The photocatalytic rate (K) of CaTi2O5 shuttle-like structure reaches 0.2001 min−1 for in 25 min methyl orange (MO) degradation under the ultraviolet (UV) light irradiation. And after combination with graphite, CaTi2O5 showed an interesting photocatalytic behavior and the photocatalytic activity of 99.8% under visible light at 100 min.
