All AB2O4 compounds exhibit a cubic crystal structure with cell parameters of a spineltype structure with space group Fd3𝑚 #### . The XRD patterns shown in Figure ) are in agreement with the reference codes and their respective cell parameters listed in Table . For example, FeCo2O4 has a cubic crystal structure with cell parameter a = 8.2440 Å and space group Fd3𝑚 #### (reference code 98-009-8552). In all samples, the characteristic peaks at ~19°, 31°, 36°, 38°, 44°, and 65° correspond to the 111, 022, 113, 222, 004, and 044 phases, respectively. The calculated crystallite sizes, determined using the Scherrer formula from the FWHM values of the spectra shown in Figure The structure of the samples is further explored using Raman spectra. Figure illustrates the Raman spectra of FeCo2O4 supported over SiC-Pretrt. The spinels prepared in this work crystallize in space group Fd3𝑚 #### , and the following active modes are predicted: The BET surface area and pore size distribution of all prepared samples are determined through BET and BJH analysis. Figure and Table illustrate the BET surface area and pore distribution results for each sample. The pore sizes of the synthesized catalysts indicate that they belong to the mesoporous category (with pore sizes ranging from 2-50 nm). The FeCo2O4/SiC-Pretrt catalyst sample exhibits a relatively higher surface area and pore volume than CoFe2O4/SiC-Pretrt, making it more accessible during reactions at elevated temperatures.
