The pollution of different water sources has become an increasing problem over the last few years. This can possibly be counteracted through the use of titanium dioxide (TiO2) nanoparticle catalysts. This reactions occurs primarily through photocatalysis. There are three different shapes of TiO2 that are being tested: anatase, rutile, and brookite. Of these three types, brookite is the least known and was the focus of this study. First, a calibration curve had to be created to track the degradation of Trichloroethylene (TCE) using a gas chromatography-mass spectroscopy (GC-MS). This was originally done for anatase and rutile nanoparticles, and compared to existing literature. Then, these results were compared to that of brookite nanoparticles.
