CO2 reforming of methane over Pt–Ni/Al2O3 catalysts: Effects of catalyst composition, and water and oxygen addition to the feed

Recent Scientific Progress on Developing Supported Ni Catalysts for Dry (CO2) Reforming of Methane

“…The noble metals, such as Rh, Pt, Ir, Pd, and Ru, exhibit higher catalytic activity and stability for DRM reactions when compared to other transition metal-based catalysts (Co and Ni) [15,16]. It has been also proved that an addition of small amount of noble metals into transition metal-based catalysts resulted in enhanced catalytic performances [9,[16][17][18][19][20][21][22]. However, to realize the industrial implementation of CRM reaction, the utilization of noble metals should be avoided due to their high cost and limited availability.…”

“…CO 2 can be considered as a possible carbon source in chemical industry and CO 2 reforming of methane (CH 4 ), which is often referred as dry reforming of methane (DRM), has been attracted much attention [8][9][10][11][12][13]. In the DRM reaction, two major greenhouse gases (CH 4 and CO 2 ) are converted into H 2 and CO.…”

Co and Ni supported on CeO2 as selective bimetallic catalyst for dry reforming of methane

“…Current research is mainly addressed to reduce carbon formation in different ways: i) by choosing supports with high mobility of oxygen ions that can react with adsorbed carbon species, as for instance CeO 2 and CeO 2 eZrO 2 solid solutions [9e11,15]; ii) by modifying the surface properties with additives, as potassium or sodium, that impart basic character, even though they lower the catalytic activity [22e24]; iii) by using multi-metallic catalysts. For example, the addition of precious metals (Pt, Rh, Ru) with nickel enhances both catalytic activity and long-term stability [25,26]. Among non-noble metals, the combination of cobalt and nickel supported on ZrO 2 and Al 2 O 3 already showed an enhancement of catalytic performance towards the methane reforming reaction, ascribed to a synergic effect due to the formation of CoeNi alloy [16e21].…”

Mesoporous catalysts for dry reforming of methane: Correlation between structure and deactivation behaviour of Ni-containing catalysts

“…However, the major drawback of this catalytic process up to now remains the rapid deactivation of the catalysts originating from the sintering of the metal active sites as well as the carbon deposition [7,8]. The most used catalysts are invariably Ni-based catalysts supported on an alumina-based carrier.…”
