Summary

Various alumina and Ga-alumina samples were synthesized by sol-gel and mesoporous material synthesis techniques employing Lauric acid and Pluronic P123. the pore properties of the aluminas were thoroughly characterized using various analytical techniques including BET, XRD, SEM and TEM. the surface area of the materials varied between 117–460 m2/g, pore diameter between 2.1–18.2 nm and pore volume between 0.27–1.24 cm3/g. the Lean-NOX performance of the synthesized aluminas was evaluated on a powder test bench system using propene as a reductant. the materials' deNOx performance was sensitive to synthesis conditions and varied from 3–68% for NO conversion and 7–82% for NO2 conversion.
