Effect of pore structure on Ni catalyst for CO2 reforming of CH4

Ni–CaO–ZrO2 catalysts with different pore structures were prepared and tested for CO2 reforming of methane. It was found that the catalyst with a mesoporous framework showed both high activity and stability. In particular, no deactivation was observed at a period of run on stream. The characterization confirmed that the “confine effect” of the mesoporous structure prevented Ni particles from sintering during reaction, and as a result, the catalyst with such a mesoporous framework showed a better catalytic performance and resistance to coking.
