英文摘要	Carbon dioxide (CO2) conversion is an important yet challenging topic, which helps to address climate change challenge. Catalytic CO(2)methanation is one of the methods to convert CO2, however, it is limited by kinetics. This work developed a structured Ni@NaA zeolite supported on silicon carbide (SiC) foam catalyst (i.e., Ni@NaA-SiC), which demonstrated an excellent performance with a CO(2)conversion of similar to 82%, being comparable to the corresponding equilibrium conversion, and CH(4)selectivity of similar to 95% at 400 degrees C. The activation energy for CO(2)conversion over the 15Ni@NaA-SiC catalyst is about 31 kJ mol(-1), being significantly lower than that of the 15Ni@NaA pelletized catalyst (i.e., similar to 84 kJ mol(-1)). Additionally, the structured catalyst was highly stable with sustained CO(2)conversion at 78.7 +/- 1.4% and selectivity to CH(4)at 97.7 +/- 0.2% over an 80 hr longevity test. In situ diffuse reflectance infrared Fourier transform spectroscopy-mass spectroscopy characterization revealed that catalysis over the structured catalyst proceeded primarily via the CO free mechanism.
