![عکس صفحه اول مقاله: Influence of the synthesis method on structural properties and catalytic activity for oxidation of CO and C3H6 of pirochromite MgCr2O4 Influence of the synthesis method on structural properties and catalytic activity for oxidation of CO and C3H6 of pirochromite MgCr2O4](/preview/png/42116.png)
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.
Pirochromite MgCr2O4 has been prepared by three different methods, characterized and examined for C3H6 and CO combustion. The work shows that novel microemulsion synthesis is able to yield high surface area material with enhanced catalytic properties for the mentioned combustion processes.Figure optionsDownload high-quality image (127 K)Download as PowerPoint slide
