Synthesis and evaluation of hexaaluminogallate/solid oxide electrolyte laminates for NOx reduction

Abstract

Hexaaluminogallates have capacity for transition metal ions in its structure and tendency to grow as plate-like particles with high thermal stability. Up to now, we reported the chemical processing for the preparation of hexaaluminogallate catalysts substituted with transition metals by coprecipitation method and their NO_x removal activities in NO/O₂ and NO/O₂/C₃H₆ reactions. In this study, we will report the NO_x removal activity of hexaaluminogallate/solid oxide electrolyte laminated composite.
