Influence of coating method on catalyst activity of AgCl/Al2O3/SUS304 composite plate

The γ-Al203 and AgCl/Al203 catalyst powder were coated on a stainless steel substrate by dip coating and electrophoretic deposition method. And AgCl/Al203 catalyst was produced by three kinds of methods, and the difference between the NOx reduction catalysis of the coated sample was compared. XRD and SEM were used to study the crystalline structure and cross-section of the coatings. The coating of γ-Al203 with the thickness of 3-5 μm and AgCl/Al203 catalyst with the thickness of 5-9 μrn were made on the surface of SUS304 plate without exfoliation. The NOx conversion of the coated sample with catalyst was about 70% at the maximum.
