EFFECTS OF PREPARATION METHODS FOR V2O5-TiO2 AEROGEL CATALYSTS ON SELECTIVE REDUCTION OF NO WITH NH3
IntroductionThe emission of nitrogen oxides (NO, NO2 and N2O) produced during high temperature combustion processes, from both mobile and stationary sources, is one of the most important current environmental issues that concerns the scientific community. The selective catalytic reduction with ammonia (NH3-SCR) is one of the most effective post-treatment for the abatement of Nox emission to the atmosphere 1. Among NH3-SCR catalysts, V2O5 supported on TiO2 is generally recognized as the most active and selective catalyst. It is well-known that TiO2 can be obtained only with a relatively low specific surface area and less thermal and mechanical resistance than other oxides, such as for example silica. To overcome this, the sol gel method has been proposed as an alternative to synthesize catalysts with a high surface area and stable active phase 2. In this view point aerogels which can be prepared via the sol-gel method and the subsequent removal of solvent by supercritical drying have attracted much attention as catalyst supports. Until now, some works have been reported to apply titania-based aerogels to NH3-SCR 3-6.
