WebAs we all know, the massive emission of carbon dioxide has become a huge ecological and environmental problem. The extensive exploration, exploitation, transportation, storage, and use of natural gas resources will result in the emittance of a large amount of the greenhouse gas CH4. Therefore, the treatment and utilization of the main greenhouse gases, CO2 … Web24 dec. 2024 · Through Ni-M alloy formation, or the intricate synergy between two adjacent metallic phases, new high-performing and low-cost methanation catalysts can be obtained. This review summarizes and critically discusses recent progress made in the field of bimetallic Ni-M (M = Fe, Co, Cu, Ru, Rh, Pt, Pd, Re)-based catalyst development for the …
Web19 jan. 2024 · The cobalt-based oxide catalysts achieved higher CO 2 yields than the iron-based oxide catalysts below 225 °C. The highest CO 2 yield (100%) was achieved over Co 3 O 4 between 150 and 175 °C, however, undesired CH 4 formation was only observed over this catalyst due to the formation of bulk fcc and hcp Co 0 between 200 and 250 °C.
