Investigation of Water and Sulfur Tolerance of Precipitable Silver Compound Ag/Al₂O₃ Catalysts in H₂-Assisted C₃H₆-SCR of NOx.

ABSTRACT: Ag/Al₂O₃ catalysts containing different precipitable silver compounds (AgCl, Ag₂SO₄, and Ag₃PO₄) were synthesized and investigated for NOx reduction in H₂-assisted C₃H₆-selective catalytic reduction (SCR). The samples were systematically characterized by N₂ adsorption, X-ray diffraction (XRD), UV-Vis, X-ray photoelectron spectroscopy (XPS), and high-resolution transmission electron microscopy (HR-TEM). N₂ adsorption revealed that the introduction of anions (Cl^-, SO₄ ^2-, and PO₄ ^3-) did not significantly affect the surface and structural properties of the Al₂O₃ support. However, XRD patter
