and Figure of Supplementary Information (SI), and the catalyst pellet is prepared in the ranges of 0.5-0.6 mm. The reaction performances of the dispersed samples (~1.0 g) are evaluated in a quartz continuous flow reactor at temperatures ranging from 1023 to 1173 K and The phases and lattice structures of the prepared nanoparticles are determined through XRD pattern analysis. As depicted in Figure , the XRD patterns of all samples show similar peaks corresponding to the standard AB2O4 spinels, which are in good agreement with reference ICDD (International Centre for Diffraction Data) numbers as shown in Table .
