The performance of a set of bimetallic Ru-Co catalysts dispersed on the TiO 2 anatase phase, synthesized by the co-deposition–precipitation with urea method, was tested in the CO 2 production by the entire oxidation of C 3 H 8 . The presence of properly dispersed ruthenium nanoparticles on a Co/TiO 2 -anatase support was notably favorable for enhancing the C 3 H 8 activity/selectivity. Likewise, an increase in the combined acidity (Brönsted and Lewis) was also observed, and the interaction between Ru 0 -CoO x species stabilized on TiO 2 prompted the C 3 H 8 oxidation at low temperature. The performance of bimetallic Ru-Co/TiO 2 catalysts was enhanced by increasing Ru 0 species and loading, showing more efficient C 3 H 8 oxidation by the combination of Ru 0 -CoO x , as revealed by DRIFTS, XPS, H 2 -TPR, and HAADF-STEM characterization outcomes. The higher acidity of the catalysts containing Ru (1.5 wt%) and Co (3 wt%) as well as the reducibility enhancement of the Ru and Co species led to the best capacity of these catalysts for C 3 H 8 oxidation to CO 2 under the experimental conditions employed in this study.
