%X This work proposes the synthesis of the 5%wt Ru on MWCNT catalyst and the influence of feed rate and testing variables for low-temperature oxidation affecting the CO<sub>2</sub> yield. Morphology and incorporation of the nanoparticles in carbon nanotubes were investigated by specific surface area (BET method); thermogravimetric analyses (TGA); X-ray diffraction; Raman spectroscopy, transmission electron microscopy (TEM) and XPS. The conversions of CO and O<sub>2</sub> were mostly 100% in groups C1 and C2 (temperature between 200 and 500<span style=\"white-space:nowrap;\">&amp;#176</span>C with low WHSV). In order to assess the effect of mass on catalytic activity, condition C3 was tested at even lower temperatures. In the tested catalyst, high activity (100% CO and O<sub>2</sub> conversion) was observed, keeping it active under reaction conditions, suggesting oxi-reduction of the RuO<sub>2</sub> at surface without affecting the MWCNT but Lewis acid influencing the CO<sub>2</sub> yield.
