TiO2 Photocatalysis Using. Weak UV Light.

Photocatalytic degradation of amoxicillin, ampicillin and cloxacillin antibiotics in aqueous solution using UV/TiO2 and UV/H2O2/TiO2 photocatalysis

TiO2 photocatalysis

It is known that TiO2 exhibits good photocatalytic properties which could be used in various commercial applications such as water and air purification or photo-induced biodegradation of microbes. TiO2 occurs in nature in the form of three crystal polymorphs: anatase, brookite and rutile. For photocatalytic applications only anatase and rutile are of interest, however anatase shows greater phot...

Plasmon enhanced visible light photocatalysis for TiO2 supported Pd nanoparticles.

A photocatalyst consisting of nanostructured Pd photochemically deposited on 20 nm TiO2 displays a reaction half-life for rhodamine b decolourisation of 0.5 minute compared to the 9.4 minutes for unmodified P25 under identical reaction conditions. We associate this increased decolourisation rate to the increase in solar light harvesting which we have measured at 8% due to a significant red shif...

MoO3 and Cu0.33MoO3 nanorods for unprecedented UV/Visible light photocatalysis.

Single crystalline MoO(3) and Cu(0.33)MoO(3) nanorods have been synthesized in large quantities via hydrothermal route, which exhibit unprecedented photocatalytic performance for the decomposition of Toluidine blue "O" (TBO) and chlorobenzene both under visible and UV light irradiation.

Carbon-modified TiO2 for photocatalysis

Here we present a method to produce TiO2 nanocrystals coated by thin layer of graphitic carbon. The coating process was prepared via chemical vapor deposition (CVD) with acetylene used as a carbon feedstock with TiO2 used as a substrate. Different temperatures (400°C and 500°C) and times (10, 20, and 60 s) of reaction were explored. The prepared nanocomposites were investigated by means of tran...
