Study on the Photocatalytic Oxidation of Gaseous Isopropanol by Ag/TiO2

Chih-Ming Ma and Kae-Long Lin
Abstract—Volatile organic compounds are typical gaseous emissions from various industries and pose hazards for human health and environment. Many technologies currently used for the treatment of volatile organic compounds, such as adsorption and scrubbing processes, simply migrates the pollutants from gas phase to another phase. Oxidation is considered to be the most effective way to decompose volatile organic pollutants and various oxidation processes have been studied, developed and implemented for several decades. However, a define need still exists for developing innovative oxidative methods that are prevailingly applicable to most volatile organic compounds. Many researchers have reported the feasibility and reaction mechanisms of titanium dioxide based photocatalytic decomposition of several gas phase organic compounds. However, recombination between electron/hole pairs resulted in low quantum yields for most photocatalytic reactions. In this study, the gaseous Isopropanol were decomposed by UV/Agtitanium dioxide process. In this system, the experimental results indicated that the deposition of 0.04% Ag on TiO2 film showed the highest photocatalytic activity among all the composition investigated.

Index Terms—Photocatalytic, titanium dioxide, VOC.
