Effect of decomposition of catalyst precursor on Ni/CeO2 activity for CO methanation

Highly Efficient LaxCe1–xO2–x/2 Nanorod-Supported Nickel Catalysts for CO Methanation: Effect of La Addition

“…As a result, it will facilitate the dissociation of CO molecules and eventually improve the CO conversion in the methanation reaction . In addition, the formation of oxygen vacancy contributes to improving the CH 4 selectivity by preventing the formation of CO 2 due to the reaction of adsorbed oxygen with CO, which is in line with our previous work …”

Structural effect of Ni/TiO2 on CO methanation: improved activity and enhanced stability

“… 3,4 We have previously confirmed that the DBD plasma decomposition of the nickel precursor, followed by thermal hydrogen reduction (in the absence of the plasma), leads to ZrO 2 and CeO 2 -supported Ni catalysts with improved low temperature activity for CO methanation 4,29 as well as CO 2 methanation. 39,40 The present work further shows the viability of the plasma decomposition of the nickel precursor for the creation of the supported Ni catalyst with improved activity and enhanced stability for CO methanation with the use of neither additional promoters nor complex supporting materials. The plasma-decomposed Ni catalysts provide us with excellent model catalysts for the study of the structural effect on the activity and stability of methanation.…”

Silica-Decorated NiAl-Layered Double Oxide for Enhanced CO/CO2 Methanation Performance

“…Compared with the NiAl-LDO catalyst, the reduction temperature of the SiO 2 -NiAl-LDO catalysts was significantly lower. The H 2 was consumed at temperatures below 550 °C, indicating that the catalyst was easily reduced, whereby more metallic Ni was generated, which plays an important role as an active component for the methanation reaction [ 48 , 49 ].…”
