Abstract
Many studies have been conducted on methods to remove air pollutants. Among them, a representative commercial technology for reducing nitrogen oxides (NO_X) is selective catalytic reduction (SCR) using NH₃ as a reductant. However, the NH₃-SCR technology has problems, such as the need for additional NH₃ gas (Active-SCR), the fact that..... More

Abstract
Recently, directly emitted NOx upon start-up has been spotlighted as a significant emissions problem. BaO loaded V2O5-WO3/TiO2 Selective Catalytic Reduction (SCR) catalysts were synthesized with various contents of barium which was a representative NOx adsorbent and their NOx adsorption, desorption, and removal efficiency were shown. The phase of BaO was..... More
