Assessment of the Synergetic Performance of Nanostructured CeO(2)-SnO(2)/Al(2)O(3) Mixed Oxides on Automobile Exhaust Control

In order to control diesel exhaust emission, CeO(2)-SnO(2)/Al(2)O(3) (CTA) mixed oxides were prepared and coated on perforated stainless steel (SS) filter plates, and the catalytic activities were analyzed in this work. The CeO(2)-SnO(2) (different compositions of Ce/Sn—2:8; 1:1; 8:2) composites and Al(2)O(3) were prepared separately via a co-precipitation approach, and CeO(2)-SnO(2)/Al(2)O(3) (CTA) mixed oxides were attained by mechanical mixing of 75 wt% CeO(2)-SnO(2) composites with 25 wt% Al(2)O(3). X-ray diffraction (XRD) and Raman spectroscopy were performed for all three CeO(2)-SnO(2)/Al(2)O(3) (CTA) mixed oxides; the CeO(2)-SnO(2)/Al(2)O(3) (Ce/Sn-1:1) sample confirmed the presence of cubic and tetragonal mixed faces, which enhances the redox nature (catalytic activities). Various characterizations such as high-resolution transmission electron microscopy (HRTEM), Brunauer–Emmett–Teller (BET) analysis, X-ray photoelectron spectroscopy (XPS), and a scanning electron microscope (SEM) were employed on CeO(2)-SnO(2)/Al(2)O(3) (Ce/Sn-1:1) sample to investigate the structural, textural, compositional, and morphological properties. The CeO(2)-SnO(2)/Al(2)O(3) (Ce/Sn-1:1) sample was coated on a perforated stainless steel (SS) filter plate via a simple, cost-effective, and novel method, and an exhaust emission test for various compression ratios (CR), injection pressure (IP), and load (L) was completed using an AVL Digas analyzer. The CeO(2)-SnO(2)/Al(2)O(3) (Ce/Sn-1:1) sample, with a size of 10.22 nm and a high surface area of about 73 m(2) g(−1), exhibit appreciable catalytic properties.
