Abstract

The high cost of commercially available photocatalysts such as P25 Degussa limits the economic feasibility of photocatalytic materials for wastewater treatment. As such, research is being done on developing a cheap method of making photocatalysts. This paper explores the fabrication of anatase titania using a facile hydrothermal method, and metallizing it with silver to improve its photocatalytic activity. The resulting powders were then characterized using Raman spectroscopy and the photocatalytic activity was evaluated via the degradation of Methyl Orange solutions in UV light. The experiment resulted in the fabrication of TiO₂ powders in both the anatase and rutile phases. The anatase TiO₂ powder was shown to be photocatalytic and metallizing it with silver at 18 weight percent enhanced both the raman spectra and photocatalytic activity of the anatase powder.
