2012, Master of Science, Miami University, Environmental Sciences.
Developing an energy efficient water treatment technology is a big challenge. This study investigated the catalytic activity of silver and gold modified nanoparticle (Ag-TiO2 and Au-TiO2) and unmodified nanoparticle TiO2 thin films towards photo degradation of methyl orange (MO) under illumination of natural sunlight and UV light. The degradation of MO was ~ 15 % greater in the presence of the Ag-TiO2 film than the TiO2 film, and there was negligible degradation of MO in the absence of film under sunlight. The catalytic activity of the Ag-TiO2 and TiO2 thin films to degrade MO in batch experiments diminished 9 % and 7%, respectively over five repetitions. All the experiments conducted under sunlight had better results as compared to UV light with all the film types. This novel application of silver modified nanoparticles may be useful for the efficient destruction of dissolved organic contaminants.
