Abstract
In the present work, 1.92 wt% Pd/9.68 wt% CeO<sub>2</sub>/spherical mesoporous silica (denoted as 1.92Pd/9.68CeO<sub>2</sub>/KCC-1) and 1.96 wt% Pd/KCC-1 (denoted as 1.96Pd/KCC-1) catalysts were prepared. It was found that the 1.92Pd/9.68CeO<sub>2</sub>/KCC-1 sample exhibited an excellent catalytic activity for methane combustion, which was much better than that of the 1.96Pd/KCC-1 sample. In addition, the 1.92Pd/9.68CeO<sub>2</sub>/KCC-1 sample possessed good high-temperature stability and water resistance. The enhanced methane combustion performance of 1.92Pd/9.68CeO<sub>2</sub>/KCC-1 was mainly attributed to the good dispersion of Pd species and the stabilization of the active Pd<sup>2+</sup> species and generation of more reactive oxygen species by CeO<sub>2</sub> modification. This work offers new insights into developing methane combustion catalysts with low-temperature catalytic performance and high-temperature stability.
