Characterization of Ni/SiO2 and Ni/Li-SiO2 catalysts for methane dry reforming

Influence of support on catalytic behavior of nickel catalysts in the steam reforming of ethanol for hydrogen production

“…The Ni/SiO 2 catalyst presents two reduction peaks with maximums at 450 and 610°C. The first of them is found in the zone assigned by literature to NiO species of low interaction with the support, whereas the signal at 610°C is attributed to a nickel oxide interacting chemically with the support as cited by some authors, it can ascribed to the formation of nickel silicate (Pompeo et al 2005). The Ni/ZnO catalyst presents two reduction peaks with maximums at 480 and 620°C.…”

Role of CeO2 in Rh/α-Al2O3 Catalysts for CO2 Reforming of Methane

“…The Rh catalysts show high activity for CO 2 reforming of methane and increase the resistance to carbon formation by oxidation of carbonaceous species adsorbed during the methane dissociation on the metal [10][11][12]. Another possibility to increase the durability and stability of DRM catalysts is the modification of support and the active phase by means of the addition of alkali and/or rare earth oxides [13][14][15][16]. These changes in the formulation of catalysts lead to improve stability because they inhibit the formation of carbon and metal sintering [17].…”

Temperature-programmed Studies of Coke Resistant Ni Catalyst for Carbon Dioxide Reforming of Methane

“…It provides a practical and effective way for the utilization of the two major greenhouse gases (CO 2 and methane) [2]. Many catalysts, including Ni-based catalysts and supported noble metal catalysts, show excellent activity for the CO 2 reforming of methane [7][8][9][10][11]. However, from the industrial standpoint of view, it is more practical to develop Ni-based catalysts due to the low-cost and the abundant resources of nickel.…”
