Outline of Final Research Achievements

We synthesized iron (Fe) and nitrogen (N)-modified silicon carbide (Fe/N-SiC) as a novel methane (CH4) combustion catalyst by annealing Fe-deposited SiC under ammonia atmosphere at 900 °C for 3 h. The activity tests indicated that catalytic combustion of CH4 was accelerated on Fe/N-SiC compared to Fe-modified SiC (Fe-SiC). Extended X-ray absorption fine structure and X-ray photoelectron spectroscopy analyses suggested that Fe was atomically distributed and coordinated with N atoms for Fe/N-SiC. N-ligated Fe centers might facilitate the activation of molecular oxygen and the generation of active oxygen species which react with CH4, resulting in the enhancement of CH4 combustion activity.
In addition, we prepared nickel (Ni)-modified nitrogen (N)-doped graphene (Ni-N-Gr) as a selective electrocatalyst for the reduction of CO 2 to carbon monoxide (CO).
