   Postech Environmental Catalysis Laboratory (PECL)

   The removal of nitrogen oxides (NOx) from stationary or mobile sources has become an important issue. For the    reduction of the NOx emission, selective catalytic reduction and three waty catalyst technology offers the best choice for combining low emission values; high removal efficiencies; and long-term, cost effective compliance. SCR system can be classified into three categories according to the nature of reductant and applications. Our group is mainly interested in the overall SCR and TWC system including the preparation of optimized catalytic materials, characterization of prepared catalyst, investigation of reaction mechanism, reaction kinetics and modeling of TWC process. Specific research areas in PECL (Postech Environmental Catalysis Laboratory) are followings
   

   Selective Catalytic Reduction (SCR)

    - NH 3 (Urea) / SCR

    - HC / SCR

   

    Three-way Catalysts (TWC)

   - Development of reaction kinetics on modern Three-way catalyst

    - Thermally stable Rh based catalytic system for an advanced modern TWC



   NOx Storage and Reduction Catalyst
