The mixed phases of CeO2 and MgO with controlled gel composition in the course of synthesis were characterizedby the Rietveld refinement, which quantitatively through synthesis had been characterized by the Rietveld refinement, which quantitatively analyzed the composition ratio of CeO and MgO as summarized in Table 1 [314]. analyzed the composition ratio of CeO2 2 and MgO as summarized in Table 1 [314].Figure 1.

The (B) Au-supporting CeO2 g(OH)two before H treatment, and (C) Au-supporting CeO2 g(OH)two H2 treatment. The g(OH)two supports with various Ce:Mg ratios had been calcined at 750 ahead of supporting Au Au nanoparticles. CeO2CeO2 g(OH)two supports with diverse Ce:Mgratios had been calcined at 750 C ahead of supporting nanoparticles. The The Miller indices in black, blue, and red correspond to MgO,Mg(OH)two ,2and CeO2 , respectively. Miller indices in black, blue, and red correspond to MgO, Mg(OH) , and CeO2, respectively.
