تاثير ماده جاذب بر بازدهي فوتوكاتاليزوري تيتانيم دي اكسيد

Conventional methods are useful for destruction of NOx and CO air pollutants but these technologies are not able to destroy solvents such as acetone, alcohol, halogenated compounds, sulfuric compounds and surfactants. These pollutions cause some problems for human, animals, plants and also for semiconductors that are used in electronic devices. Photocatalytic reactions have been found to be able to overcome the problem. In this research, a catalyst was prepared by sol-gel technique and evaluated by the amount of CO conversion. Some adsorbents were added to the catalyst to improve its conversion efficiency. The results show that, for % 80 conversion, the space time of TiO2-A1203 is 4*10^6 g.s/mol while of TiO2 catalyst is 15 *10^6 g.s/mol. As a result, it can be said that A1203 improves conversion efficiency.
