Synthesis and Characterization of Ca and Ba Doped LAMOX Materials and Surface Study by X-ray Photoelectron Spectroscopy.


(La1-xCax)2Mo2O9-d and (La1-xBax)2Mo2O9-d (x = 0.05, 0.1, 0.15, 0.2) materials were prepared at 800 °C by co-precipitation method and characterized by X-ray diffraction and scanning electron microscope. The XRD diagrams showed the presence of CaMoO4 and BaMoO4 secondary phases only at high contents of the dopants. X-ray photoelectron spectroscopy was used… (More)
