Summary: This study demonstrates a facile aerosol-based method to prepare hybrid nanostructures for catalyzing steam-promoted CO2 reforming with methane. The resulting NiPdOx-CeO2 nanoparticles deposited on SiO2 nanoparticle clusters exhibit superior catalytic performance at low temperatures, with high turnover frequency, tunable H2/CO ratio, and long-term operation stability. Incorporating SiO2 nanoparticle clusters as support material helps to enhance the dispersion of active metals and suppress metal sintering.

Summary: In this study, Cu@S-1 catalyst was successfully prepared using a ligand-stabilized strategy, and it showed higher activity and stability in the methanol steam reforming reaction compared to the Cu/S-1 catalyst prepared through conventional impregnation. Comprehensive characterization studies revealed that the advantage of this catalyst lied in the enhanced dispersion of Cu species and a higher Cu+ ratio.

Summary: This study analyzed the methanol synthesis performance using CO2 and syngas as feedstock, finding that increasing reactor diameter can enhance methanol yield but large pressure drops may reduce the yield. Removing water and increasing reaction temperature were found to increase methanol yield and CO2 conversion. Additionally, higher CH4 content in the biogas can lead to higher methanol production and using a higher recycle ratio for unreacted syngas can enhance methanol production.

Summary: Power-to-X processes convert renewable energy's free electrons into chemical bonds. Electrochemical processes increase energy demand, while directly electrified thermochemical processes reduce demand and achieve high decarbonization. Electrically heated methane reforming avoids carbon dioxide emissions. Electrically heated methane reforming can achieve negative carbon dioxide balance without carbon capture and sequestration.

Summary: Hydrocalumite derived nickel (Ni) catalysts with different loading of magnesium (Mg) were prepared and tested for ethanol steam reforming (ESR). The optimal reaction temperature for the ESR catalysts was found to be 650 degrees C, with 15Ni7.5Mg/HCa showing remarkable catalytic performance. The characterization results indicate that 15Ni7.5Mg/HCa with a certain amount of Mg loading exhibits the smallest Ni0 crystallite sizes, better H2 reducibility, and suitable basicity.

Summary: This study focuses on the application of Y-promoted Ni-based catalysts supported on bulk and hollow Al2O3 supports in the steam reforming of methane process. Various characterizing techniques were employed to analyze the catalysts. The 20Ni-3.0Y/HAl catalyst showed the highest methane conversion, hydrogen yield, and H2/CO molar ratio at 700 degrees C, possibly due to the larger surface area of the hollow alumina support compared to the bulk one.

Summary: This paper presents a microwave plasma-based technology for efficient hydrogen production from synthetic biogas. The experiment demonstrated that the waveguide-supplied metal cylinder-based microwave plasma source (MPS) could carry out the steam reforming of synthetic biogas without soot formation and microwave discharge extinction. It also introduced a new parameter, energy-CH4 feedstock consumption yield, to describe the MPS performance.

Summary: The study compares the effect of four different evaporator designs on the stable reforming of methanol-water mixtures, showing that the evaporator configuration is critical in performing stable reform reactions, especially for the flow-field mode of the evaporator. Additionally, a combination of both internal and external evaporation methods generates the highest performance for the methanol-reforming system, with methanol conversion reaching almost 98%.
