The work examines comparatively MgCr2O4 oxide samples prepared by three methods (solid state

reaction, sol–gel and co-precipitation within reverse microemulsion) with respect to their

structural/morphological characteristics and catalytic properties for complete combustion of carbon monoxide and propene. For this purpose, the samples are examined by XRD, SBET, SEM, XPS and

TPR techniques. The results reveal achievement of optimum catalytic properties for the sample prepared by microemulsion, a method which apparently allows achievement of high surface area nanocrystals in this type of material.
