Vanadium oxidation states controlled in aqueous solution and hexagonal boron nitride for selective catalytic reduction of NO by NH3 |
초록 |
Technology has advanced, and fossil fuel consumption has naturally increased. Various and plenty of exhausted gaseous contaminant adversely affect not only environment but organisms, and NOX is especially regulated due to its own maleficence. A commonly abatement technology of NOX is selective catalytic reduction with NH3, and V-based catalyst is commercialized on TiO2. However up to present, because operating temperature is the range of 300-380 °C, necessary of modified V-based catalyst capable of operation in lower temperature due to further tighten regulation in future. Generally, vanadium exhibits four oxidation states, among which V4+ and V3+ show better SCR performance than general V5+. Therefore, vanadyl species are main factor in modifying V-based catalyst, and SCR performance is further enhanced by deflocculated particle on porous h-BN in addition to following variable: calcination condition, and aqueous pH. |
