NOx from the thermal power plants are NO and NO₂. This work investigated the chemical/physical characteristics and SCR efficiency of newly prepared catalysts including tungsten (WO₃), molybdenum (MoO₃) and antimony (SbO₃) based on vanadia(V₂O5) over titania(TiO2). As a result of the examination, the surface area of the catalysts promoted with additional metals was larger and the de-NOx efficiency also was enhanced with temperature. The most efficient catalytst was V₂O5/TiO₂-WO₃(10%) at 200 °C. Such a high efficiency could contribute to reduce the ammonia slip.
