Catalytic performance of Yttrium-doped Co/Mesoporous Alumina Catalysts for Methane Dry Reforming

A series of mesoporous alumina (MA) supported cobalt-based catalysts with different yttrium promoter (0-5 wt.%) loading was synthesized by sequential incipient wetness impregnation (SIWI) approach and extensively investigated for methane dry reforming (MDR) reaction. The characterization results con...
