| 摘要: |
Ni/SiC and La2O3 modified Ni/SiC were prepared by impregnation method and used as the catalysts for
methanation of CO2. The modified Ni/SiC shows better catalytic activity and stability than pure Ni/SiC. XRD
and TPR results indicate that La2O3 can effectively restrain the growth of NiO nanoparticles, improve the dispersion
of NiO and strengthen the interaction between NiO and SiC. XPS result suggests that La2O3 can change
the electron environment surrounding Ni atoms and thus reactant CO2 on the Ni atoms can be activated more
easily. |
