“…However, this method involves complex complicated processes, including multistage water-gas shi, decarburization, and post-hydrogen purication. 6,7 In addition, the need of enormous auxiliary fuel to maintain the strong endothermal reaction would also lead to signicant CO 2 emission. 8 In comparison, electrocatalytic water splitting allows hydrogen to be prepared at room temperature and is recognized as a possible method to replace SMR for hydrogen generation.…”

“…As observed, the Ni/Y x Ce y Ru z O 4 catalyst is stable and shows a rather high capability of maintaining its activity during 30 h of current flow at 700 °C and has continued its activity with the least deactivation. The presence of Ce–O in the support structure increases oxygen deficiency due to Ce 3+ in the lattice and results in oxygen mobility to prevent coke formation and increase stability , of the Y x Ce y Ru z O 4 support structure. The Y in the structure stabilizes pore and lattice framework and helps with better stability of the catalyst in harsh temperatures .…”

The performance of spinel Y x Ce y Ru z O 4 (x = 1.5, y = 0.84, and z = 0.04) as the catalyst support in dry and steam reforming of methane (DMR/SMR) in a monolithic microreactor has been investigated. Ni/Y x Ce y Ru z O 4 catalysts have been compared with Ni/Ce−Y−Ru−Al 2 O 3 and Ni/Al 2 O 3 catalysts in the reactor test in terms of catalyst activity and stability under identical conditions. The structural features of the catalyst including surface area, morphology, and crystalline structure have been investigated using BET, XRD, XPS, TEM, FE-SEM, EDX, ICP, TPR, TGA, and TPD analyses. Y x Ce y Ru z O 4 shows that a good dispersion of the active nickel metal on the catalyst support will result in higher efficiency and activity, low temperature reduction, higher active BET surface area, and higher pore volume. The catalytic activity for SMR and DMR reactions is in the order Ni/Y x Ce y Ru z O 4 > Ni/Ce−Y−Ru−Al 2 O 3 > Ni/Al 2 O 3 . The highest methane conversion (93%) in addition to very low coke formation is obtained using Ni/Y x Ce y Ru z O 4 , which is a significant achievement in comparison to previous DMR and SMR catalysts.

Metal–organic frameworks (MOFs) have attracted a lot of attention in various applications such as molecular separation, catalysis, and gas delivery, due to their unique properties such as controllable structure, significantly specific surface area, and extensive porosity. However, conventional synthesis methods yield powdered MOFs, which cannot be directly used in the adsorption separation process due to such limitations as a high pressure drop, low mass transfer rate, and poor recyclability with scattering tendencies. Thus, it is crucial for practical applications to shape MOFs into various monoliths that allow an efficient processing, especially for industrial purposes. The existing forming methods are used to shape MOFs into films, pellets, tablets, gels, and honeycomb forms. At the same time, the shaping processes are generally accompanied by varying degrees of performance degradation of the original MOFs material, which is manifested in terms of loss of its adsorption capacity by a decrease in the specific surface area and porosity. Consequently, it is important to shape MOF monoliths into the appropriate shapes, mechanical strength, and stability, as well as to prevent the loss of the original properties in industrial applications. This paper reviews various strategies for shaping MOFs and discusses the impact of the shaping process on the properties of the MOFs as compared to their pristine powder form. It is believed this review will facilitate the industrial application of MOFs in gas processing applications.
