Facile one-step synthesis of mesoporous Ni-Mg-Al catalyst for syngas production using coupled methane reforming process

Development of Co Supported on Co−Al Spinel Catalysts from Exsolution of Amorphous Co−Al Oxides for Carbon Dioxide Reforming of Methane

“…The pulsation is continued until the adsorption of H 2 reached the saturation value. The total metal dispersion of Co metal was calculated using Equation (7).…”

“…In dry reforming, metal elements from group VIII such as Ru, Rh, Ni, Co, and Pt are catalytically active . Among them, Ni‐based catalysts are widely investigated due to low cost and relatively high activity . However, Ni is prone to coke deposition and particle sintering .…”

“…[1][2][3][4] Among them, Ni-based catalysts are widely investigated due to low cost and relatively high activity. [5][6][7][8] However, Ni is prone to coke deposition and particle sintering. [9] Coke deposition originates mainly from CH 4 decomposition [Eq.…”

“…Recent studies on the application of common support materials for Co and Ni catalysts in dry reforming have demonstrated that the performance of support decreased in the order of Al 2 O 3 > MgO > SiO 2 > ZrO 2 > TiO 2 . [1,7,20,21] The superior activity of Al 2 O 3 and MgO is most likely resulted from their strong metal-support interaction, providing several advantages such as improve catalyst stability, prevent active metal sintering and promote CO 2 conversion. [6,7,20,22,23] Particularly, Co supported on Al 2 O 3 catalysts have constituted an important class of catalytic materials and have been widely examined owing to their high abundancies, excellent catalytic activities, and good resistance towards carbon deposition.…”

[24] Al 2 O 3 is able to induces high dispersion of the Co metal to prevent the sintering of active sites, thereby preserving the activity of Co. [25,26] With reference to Co/Al 2 O 3 catalysts, different preparation methods and metal loadings have been examined to yield catalysts with diverse structures and reactivities toward dry reforming.…”
