Abstract

Using Tetrabutyl titanate (TBOT) as titanium source, the nanocrystal TiO2 was synthesized via hydrolysis deposition processing in cationic surfactant system at room temperature. The synthesized products were characterized by TEM and XRD. Photocatalytic degrade to NPE-10, phenol and DBS in solar irradiating were studied, respectively. The TiO2 powder showed excellent photocatalytic property. It was different to degrade three substances. NPE-10 was degraded nearly 70% in 2 hours, phenol was degraded nearly 95% in 8 hours, DBS was degraded nearly 82% in 8 hours.

Kurzfassung

Mittels Tetrabutyltitanat (TBOT) als Titan-Quelle wurde nanokristallines TiO2 durch eine Hydrolyse-Depositions-Aufbereitung in einem kationischen Tensidsystem bei Raumtemperatur synthetisiert. Die dargestellten Produkte wurden mittels TEM and XRD charakterisiert. Der photokatalytische Abbau von NPE-10, Phenol und DBS wurde jeweils bei Sonnenbestrahlung untersucht. Das TiO2-Pulver zeigte ausgezeichnete photokatalytische Eigenschaften. Der Abbau der drei Substanzen verlief dabei unterschiedlich. NPE-10 wurde in 2 Stunden zu ca. 70%, Phenol in 8 Stunden zu ca. 95% und DBS in 8 Stunden zu ca. 82% abgebaut.

Key words:: Cationic surfactant; nanocrystal TiO2; photocatalytic degradation
