제목 The catalytic effect of V2O5-WO3/TiO2catalysts by dry synthesized process using high energy ball milling method​
초록 Recently, Environment pollution is aworldwide problem, and it has a direct impact on the health of human population.It is resulted from NOx, SOx, CO, which are harmful tohuman body and NOx reacts with hydrocarbon causing photochemicalsmog. Selective Catalytic Reduction (SCR) is one of innovative technique forreducing NOx to H20 and N2 by blowing NH3gas under catalyst condition. Ingeneral, wet impregnation method is used to produce catalyst, which is a methodof making a catalyst through the process of mixing solutions. It is simple,however, it is hard to control the particle size of the catalyst which affectsthe catalyst efficiency. Therefore, we have demonstrated V2O5-WO3/TiO2catalyst by high energy ball milling method, which can control particle sizeand morphology of catalyst. The surface property is confirmed by SEM and BET,and the catalyst property is characterized by fixed bed reactor.
