Abstract

In this study, the catalytic activities of Raw CNTs and Co/CNTs for CO removal were determined between 100 and 300°C. To confirm the characterization of Raw CNTs and Co/CNTs, the composition and morphology of two catalysts were analyzed by using XRD, SEM, TEM and Raman spectra. The results showed that the CO conversion was 98% by using Raw CNTs at 250°C and this conversion was similar to that of using Co/CNTs. Since no purification and no re-immersion steps are needed for the preparation of Raw CNTs, this application can save the preparation procedures and reduce the waste yields and costs.
