Summary: Three types of ruthenium-supported catalyst beads (Ru/Al2O3, Ru/La2O3-Al2O3 and Ru/La2O2CO3-Al2O3) were synthesized and tested for ammonia decomposition. The Ru/La2O2CO3-Al2O3 beads showed significantly higher catalytic activity compared to the Ru/Al2O3 and Ru/La2O3-Al2O3 beads. This can be attributed to the addition of La, which facilitated electron donation from the bead surface to the Ru particles, leading to an increased rate of N2 desorption. The presence of La2O2CO3 as a surface coating had favorable properties, such as limiting the penetration of Ru particles into the catalyst bead core and increasing the surface metal concentration.

Summary: In this study, CO2 reforming of methane was investigated over Ni and/or Ru supported on KIT-6 and Ce-promoted catalysts. It was found that Ce promotion led to destruction of porous structure and impaired interactions between active phase and support, but increased the basicity of the catalysts. Among the non-promoted catalysts, Ni-Ru/KIT-6 showed better catalytic performance, while the Ce-promoted Ni-Ru/Ce-KIT-6 catalyst exhibited higher activity and stability.

Summary: This study compares the combustion and emission characteristics of methane mixed with steam and the products of methane reforming with steam. The results indicate that syngas combustion occurs at higher temperature and emits more NOx compared to methane combustion, but adding steam to the fuel inlet can reduce emissions for both methane and syngas.

Summary: High-purity hydrogen used in chemical vapor deposition often contains methane impurity, which negatively impacts device performance. To remove methane, the commonly used ZrMnFe getter is not efficient enough at high temperatures. To address this, Co partially replaces Fe in the ZrMnFe alloy. The ZrMnFe0.7Co0.3 alloy demonstrates excellent methane reactivity and can significantly reduce methane levels in hydrogen and helium gases.

Summary: The paper examines an integrated solar combined cycle system (ISCCS) utilizing solar energy for steam methane reforming and compares its overall efficiency with that of a system utilizing solar energy for steam generation in a steam turbine cycle. Utilizing solar energy for steam methane reforming increases the overall efficiency by 3.5%. If water used for steam methane reforming is condensed from the exhaust gases, the overall efficiency of ISCCS increases by 6.2% to 8.9% compared to the system where solar energy is used for steam generation in a steam turbine cycle. Sankey diagrams based on the energy balance were compiled. Utilizing solar energy for steam methane reforming increases the power share of a gas turbine cycle, with two-thirds in the gas turbine cycle and one-third in the steam turbine cycle.

Summary: Blue hydrogen production by steam methane reforming (SMR) with carbon capture is the most commercially viable method, and sorption-enhanced steam methane reforming (SESMR) can further decrease the cost of H2 production. Introducing additional metal elements to improve the performance and prevent catalyst deactivation has been an effective solution. This review summarizes recent developments and highlights the potential of bi/polymetallic catalysts for SMR.

Summary: This study explores the discriminative activities and mechanisms for activation of O-O bond in peroxy compounds via single-atom catalysts (SACs) with higher coordination numbers (M-N5). The atomic catalyst (Fe-SAC) with Fe-N5 as the active center was constructed, effectively activating peroxymonosulfate (PMS), peroxydisulfate (PDS), and hydrogen peroxide (H2O2). The study demonstrates the degradation efficiencies of acyclovir are related to the O-O bond length in different peroxy compounds, and reveals the discriminative mechanisms for activation of O-O bond in different Fenton-like systems.
