Abstract

The Sm₂Zr₂O₇ of pyrochlore structure was studied as a catalyst for high temperature combustion. It was prepared by the sol-gel method with and without acetylacetone as a chelating agent. The order of crystallinity and the surface area were improved when acetylacetone was used. The catalytic activity of CH₄ combustion was also enhanced and superior to that of Mn-substituted hexaaluminate above 550 °C.
