Abstract

The Ga₂O₃-Al₂O₃-ZnO (GAZ) multi-component spinel powders with incorporated Cu²⁺, Co ²⁺, Fe²⁺, Ni²⁺, Mn²⁺ and In ²⁺ metal cations were synthesized by co-precipitation method from a mixed solution of nitrate salts. Spinel crystal structure of each composition was confirmed by XRD measurements. The multi-component oxide powders were tested in the reduction of nitrogen oxide (NO) under lean conditions. Among the catalysts tested, In₂O₃-containing GAZ with a pure spinel phase structure showed promising catalytic activity in the NO reduction in the presence of 10% H₂O vapor. In addition, the effect of H₂O vapor and SO₂ on the selective reduction of NO over In ₂O₃-GAZ/cordierite and In₂O₃-GAZ/ metal honeycombs catalysts has been investigated.
