Low-temperature oxidation of CO to CO 2 plays a key role in broad application prospects. In order to achieve the low-temperature oxidation of CO, the gold catalyst was prepared using Fe 2 O 3 -modified SiO 2 as support. The results showed that CO conversion was enhanced over the modified catalyst. At – 10 °C, CO conversion of 95 % could be achieved. The catalysts were characterized by XRD and TEM, and the results showed that the Fe 2 O 3 was dispersed in the form of amorphous state. Attributed to the Au-Fe 2 O 3 interaction, the modified catalyst exhibited excellent performance for the oxidation of CO. DOI: http://dx.doi.org/10.5755/j01.ms.24.3.19450
