Effects of spatially restricted Ni nanocrystals within ordered mesopores on the production of syngas

Template-Assisted Wet-Combustion Synthesis of Fibrous Nickel-Based Catalyst for Carbon Dioxide Methanation and Methane Steam Reforming

“…Recently, ordered mesoporous silica was utilized as catalyst supports for the catalytic partial oxidation of methane to produce syngas and hydrogen. 13 The 2D hexagonal ordered mesoporous structure is found to play a crucial role for homogeneous distribution of Ni nanocrystals during the preparation and revealed a good resistance against carbon deposition. The synthesis technique of catalysts is another crucial issue influencing the particle size and morphology of the catalyst, tuning its dispersion and wettability, governing possible interaction between the components, thus ultimately tuning the catalytic activity and durability of the system.…”

“…Well-organized nanoporous catalysts are of great interest because of highly ordered pore structure, high specific surface area, tailorable pore size, framework, and surface properties. , An appropriate support has to improve the dispersion of active components, promote effective metal–support interactions, and retain the unique properties of the catalyst.
