The influence of incorporating Ni with Co species in the perovskite structure was elucidated by both the catalytic performance and physicochemical properties of as-prepared materials. Several modern techniques were utilized to study the catalysts’ properties, including XRD, EDS, SEM, HR-TEM, Nitrogen adsorption–desorption, H<sub>2</sub>-TPR, CO<sub>2</sub>-TPD, and Raman spectroscopy. As Co modification content increased, respective to x value in CeNi<sub>1-x</sub>Co<sub>x</sub>O<sub>3</sub> change from 0.1 to 0.5, calcined catalysts’ crystallite size of separated M<sub>2</sub>O<sub>x</sub> oxides gradually increased from 16.2 to 20.3 nm. Investigating the CO<sub>2</sub>-TPD and H<sub>2</sub>-TPR profiles showed that CO<sub>2</sub> adsorption ability of catalysts increased while reducibility decreased when x value increased from 0.1 to 0.5. Despite clearly change of physicochemical properties, the Co content in range of <i>x</i> = 0.1–0.5 did not have significant influence on the catalytic activity in CSCRM reaction.

Finally, the pattern recognition algorithms including discriminant analysis, support vector machines, and neural network pattern recognition (NNPR) were implemented to discriminate hole cleaning efficiency following the ROP prediction process.

Additionally, the best classification performance was achieved using the NNPR algorithm with 91% accuracy and a cross-validation error equal to zero.
