Effects of structure on the carbon dioxide methanation performance of Co-based catalysts

The difference of roles of alkaline-earth metal oxides on silica-supported nickel catalysts for CO2 methanation

“…Reaction temperature inuenced signicantly the catalytic behaviors. [15][16][17][18][19][20][21][22][23][24] As shown in Table 3, CO 2 conversions depended largely on the reaction temperatures. At 350 C, carbon dioxide conversions were low and the reaction produced mostly CH 4 with small amounts of by-product CO. 43,44 With temperature increased to 450 C, the catalytic activities were improved.…”

Ordered Mesoporous CeO2‐supported Ag as an Effective Catalyst for Carboxylative Coupling Reaction Using CO2

“…During the last few decades, the excessive CO 2 emission from fossil energy conversion has caused global warming and climate change, which should be dealt with greatest attention . On the other hand, CO 2 is an important C1 source in organic synthesis owing to its nontoxicity, renewability and accessibility . Thus, the exploitation of CO 2 chemical transformations to high‐value products is identified as an attractive approach to control and reduce CO 2 emissions.…”

CO2 reverse water‐gas shift reaction on mesoporous M‐CeO2 catalysts

“…Therefore, reducing CO 2 emission levels is necessary. However, CO 2 is a cheap, non‐toxic, and abundant C1 raw material . Thus, CO 2 utilization is a promising strategy to mitigate global warming.…”

“…However, a CO 2 molecule is linear with a double bond between the carbon and oxygen atoms (O=C=O), which results in high thermodynamic and chemical stability. Moreover, byproducts can be produced if CO 2 molecules directly react with H 2 to form methane and methanol . Thus, the CO 2 RWGS reaction is considered the most potential and promising method for CO 2 utilization.…”
