Anatase TiO2 Nano-particles Preparation With Neutralization Hydrolysis Technique and Photocatalytic Performance

摘要：

A neutralization hydrolysis route has been used to synthesize titanium oxide nanoparticles.Transmission electron microscopy(TEM) and X-ray diffraction(XRD) characterization results showed the TiO2 nanoparticles were single anatase phases when calcined at 600 ℃-800 ℃ for 2h.The particle diameter ranged from 15 to 30nm.The pH value was key factor for precursor composition.When pH value 2-4,the H2TiO3 precursor with low agglomeration was obtained.As-prepared anatase TiO2 nanoparticles,during photodegradation of methylic orange under UV-light irradiation(λ.=254nm),exhibited excellent activity,more than 95.5％ methylic orange was degraded in 1h.
