Role of Mo in CO2 reforming of CH4 over Mo promoted Ni/Al2O3 catalysts

Ni catalysts derived from Mg–Al layered double hydroxides for hydrogen production from landfill gas conversion

“…The existence of NiO phases were confirmed by the XRD analysis. The NiO phases had low interaction with the MgeAl layers [22] and was easy to be reduced under H 2 atmosphere. With the increase in thermal treatment temperature, the interaction between NiO and MgeAl layers increased through solid-state reactions.…”

“…From the TEM images, it is clear that LDH-900 had the largest metal particle sizes among the samples. It has been reported by many research groups that large metal particle sizes accelerate carbon formation and deactivation [22,28,29]. The complexity of the relationship between catalyst properties and activity indicated that the landfill gas conversion reaction takes place on many active sites with different nature.…”

Effect of interactions between Ni and Mo on catalytic properties of a bimetallic Ni-Mo/Al 2 O 3 propane reforming catalyst

“…Moreover, in many studies the addition of Mo to Ni had a negative impact on catalyst activity [28][29][30], while none discussed the effect of Ni-Mo catalysts on the selectivity to different steam reforming (SR) or oxidative steam reforming (OSR) reaction products. The objective of this study was to investigate the effect of adding small amounts of Mo to a 15 wt.% Ni/Al 2 O 3 propane reforming catalyst.…”

Studies on coke formation and coke species of nickel-based catalysts in CO2 reforming of CH4

“…The reaction of methane reforming with CO 2 has gained increasing attention due to the importance of synthesis gas as a major feedstock for fuel cells and Fischer-Tropsch reaction and both natural gas and CO 2 can affect the environment and energy resources [1][2][3]. Most VIII group metals, such as Fe, Co, Ni [4][5][6], are often used as active component for the reforming reaction.…”

“…and some researchers [14][15][16] think the carbon deposition during the reforming of methane is due to either equation (1) or (2). Based on the mechanism of the reforming reaction [17]: both CO 2 and CH 4 should be absorbed and activated before the relevant bonds are broken.…”
