Dry reforming of methane to syngas over La-promoted hydrotalcite clay-derived catalysts

Alumina coated nickel nanoparticles as a highly active catalyst for dry reforming of methane

“…All catalysts prepared by ALD showed outstanding activity in comparison to benchmark dry reforming catalysts. Table S1 summarizes activities of recently published Ni catalysts for DRM [39][40][41][42][43][44][45][46][47][48][49][50][51], several of which are described as highly active, indicating the high benefits to catalytic activity of the ALD synthesis route. The higher activity of NiO-5 compared to the catalysts of Gould et al [39] (ALD with alumina supported Ni nanoparticles) can be attributed to a higher Ni: support ratio (rates per mole of Ni are the same order of magnitude), allowing for a majority Ni-nanoparticle catalyst.…”

Efficient hydrogen production from ethanol steam reforming over La-modified ordered mesoporous Ni-based catalysts

“…Reported by Serrano-Lotina et al [63], the TPR results of hydrotalcite-like compounds presented that, the increase of Mg/Al molar ratio shifted the first peak toward lower temperature and the second peak toward higher temperature owning to a strengthened interaction on the Mg-Ni-Al surface. Additionally, according to [1,64], the lanthanum element could incorporate into the alumina framework.…”

Dry reforming of methane at moderate temperatures over modified Co-Al Co-precipitated catalysts

“…This preparation method can originate mixed oxides, which have desirable properties such as high surface area, high thermal stability and small crystallite sizes 20,21 . Indeed, several nickel-spinel oxides have shown excellent results for dry reforming of methane [22][23][24][25][26][27][28] . According to Bhattacharyya et al, the mixed oxide materials derived from a hydrotalcite-type (HT) structure might provide a random distribution of the divalent metal ions (M 2+ ) in the layered structure.…”
