“…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.…”

“…The previous experimental and theoretical studies confirmed that smaller Ni particles have a better ability to suppress the carbon deposition [2,18,19]. Nevertheless, confining the Ni particle size within the nanoscale dimension is difficult, because the sintering of the Ni particles easily takes place under the severe reaction conditions of DRM [20,21].…”

A series of nickel-containing mesoporous silica samples (Ni-SiO2) with different nickel content (3.1%–13.2%) were synthesized by the evaporation-induced self-assembly method. Their catalytic activity was tested in carbon dioxide reforming of methane. The characterization results revealed that the catalysts, e.g., 6.7%Ni-SiO2, with highly dispersed small nickel particles, exhibited excellent catalytic activity and long-term stability. The metallic nickel particle size was significantly affected by the metal anchoring effect between metallic nickel particles and unreduced nickel ions in the silica matrix. A strong anchoring effect was suggested to account for the remaining of small Ni particle size and the improved catalytic performance.

“…Furthermore, all peaks gradually shifted to lower 2θ values with the increase of Ce/(Ce + Zr) molar ratios. This phenomenon suggested that the interplanar spacing and cell parameters became bigger because of the isomorphous substitution of smaller Zr 4+ (ionic radius 0.84 Å) with larger Ce 4+ (ionic radius 0.97 Å) [30].…”

Noble Metal-Free Ceria-Zirconia Solid Solutions Templated by Tobacco Materials for Catalytic Oxidation of CO

A series of ceria-zirconia solid solutions were synthesized using tobacco leaves, stems and stem-silks as biotemplates. A combination of physicochemical techniques such as powder X-ray diffraction (XRD), N 2 adsorption/desorption measurement, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were used to characterize the as-synthesized samples. The results show that the morphologies of the templates were well replicated in the obtained ceria-zirconia solid solutions. Catalytic oxidation activities of CO over the ceria-zirconia solid solutions were then investigated. The catalyst templated by tobacco stem-silk exhibited higher conversion of CO at lower temperature than that of ceria-zirconia solid solutions templated by tobacco leaves and stems or without templates due to its special morphology. The catalyst even showed similar CO conversion when compared to ceria-zirconia solid solutions doped with 1.0 wt % noble metals such as Pt, Ag and Au. The results highlighted the advantages of using tobacco as biotemplate.
