Partial oxidation of methane over CeO2 loaded hydrotalcite (MgNiAl) catalyst for the production of hydrogen rich syngas (H2, CO)

CeO2 Nanorod@NiPhy Core‐shell Catalyst for Methane Dry Reforming: Effect of Simultaneous Sintering Prevention of CeO2 Support and Active Ni

“…Textural properties of different structured catalysts were characterized by N 2 isothermal adsorption‐desorption (Figure 3). As presented in Figure 3a, all catalysts exhibit type IV N 2 adsorption‐desorption isotherms which means the existence of mesoporous structure [12] . Specifically, CeO 2 @NiPhy‐7 and CeO 2 @NiPhy‐9 show parallel N 2 adsorption‐desorption isotherms because of their similar NiPhy shell thickness as confirmed from TEM images (Figure 2A–B).…”

[12] Specifically, CeO 2 @NiPhy-7 and CeO 2 @NiPhy-9 show parallel N 2 adsorption-desorption isotherms because of their similar NiPhy shell thickness as confirmed from TEM images (Figure 2A-B). By contrast, the adsorption-desorption isotherms of CeO 2 @NiPhy-18 display obviously higher adsorbing capacity between 0.6-0.9 relative pressure, which is attribute to the thickest shell thickness and its largest specific surface area of 131.1 m 2 g À 1 (Table 1).…”

The High Performance of Multi-Metal Layered Double Hydroxides (LDHs) in the Removal of Organic Dyes

“…XRD Analysis Figure 1 displays the XRD patterns of MgNiAl-LDH (Figure 1a) and MgNiFe-LDH (Figure 1b), where both samples exhibit numerous distinct reflections, such as doublelayered hydroxide reflections, at 11.83 • , 23.44 • , 34.89 • , 38.94 • , 46.9 • , and 62.5 • , which correspond to (003), (006), (009), (015), (018), and (110), respectively. The distinctive diffraction peaks of both samples are sharp, fine, and symmetrical, indicating the single crystal phase and the high degree of crystallinity of the sample's crystal structure [23][24][25].…”

Calcination-Free Synthesis of Porous Metal Oxides/Carbon from Calcium Carbide by Ball Milling

“…According to the XRD results (Figures and S6), the phases of pure metal oxides should be stable in the temperature range of 50–900 °C, except for the escape of a few oxygen atoms; − thus, the mass loss in TGA results and the peaks in DTG curves could be induced by the combustion of carbon support in air. In other words, the carbon contents of these materials were almost equal to the total mass loss in TGA curves, which are listed in Table .…”
