Abstract

Hydrogen assisted selective catalytic reduction of NOx over Ag/Al2O3 with either hydrocarbons or ammonia as reducing agents is an emerging technology for lean NOx reduction. Herein, we present a mật độ trùng lặp từ khóa functional theory study of H2 dissociation over a representative mix of sites present on the Ag/Al2O3 catalyst. Whereas H2 dissociation over supported Ag ions and oxidized Ag surfaces is found đồ sộ be facile, dissociation over metallic Ag, defect không tính tiền Al2O3 and alumina-supported Ag is associated with high barriers. The results are rationalized by analysis of the electronic structure.
