Self-propagation high temperature synthesis: A new route for fabrication of porous Mg-doped ceriumoxide

The aim of this study was synthesis of Mg-doped porous cerium oxide powder by self-propagatinghigh temperature synthesis reaction of Mg-xCeO2-O2 system. Results indicated that doping Mg in theCeO2 crystal structure shifted the Ce-O band in the FTIR spectra from 490 to 574 cm-1. Moreover, theEDS results revealed the distribution of Mg in the CeO2 microstructure. Finally, it was inferred thatthe SHS technique can be introduced as a rapid and novel method for synthesis of Mg-doped porousCeO2 powders.
