Summary: This study analyzed the composition of biogas produced in a landfill using gas chromatography. The results showed that methane and carbon dioxide were the main components, and dry reforming of methane (DRM) could be a promising valorization method. The presence of water and VOCs could affect the catalytic efficiency, but DRM was still feasible under certain conditions.

Summary: Dry reforming of methane (DRM) is a promising process for producing synthetic gas, and the design of an effective catalyst is crucial. In this study, nickel catalysts supported by calcium hydroxyapatite (HAP) and HAP-doped magnesium (Mg_HAP) were synthesized and evaluated in the DRM reaction. The Ni/HAP and Ni/Mg_HAP catalysts showed outstanding performance due to the tunable acidity-basicity of the supports, strong metal-support interaction, and good thermal stability of nickel nanoparticles. The main products were H2 and CO, with stable selectivity around 85%, while H2O and solid carbon were byproducts with 5-10% selectivity.

Summary: The parallel electrodes gliding plasma (PEGP) is a novel approach for the dry reformation of methane, providing high conversion rates and energy efficiencies. Compared to traditional glide plasma, PEGP demonstrates superior performance in molecular dissociation. By dissipating the energy in the layers of fresh reactants gas instead of overheating or dissociating the products, higher performance is achieved.

Summary: The study demonstrates that microwave-assisted dry reforming of methane can achieve high and steady conversions of CH4 and CO2 up to 90% when using a mechanical mixture of Ni/Al2O3-SiC and Ni/SiC. Compared to steam reforming, the microwave-assisted dry reforming of methane over Ni/SiC is shown to be a competitive and cost-effective process candidate.

Summary: In this study, a surface defect-promoted Ni catalyst supported on Mg/Al hydrotalcite via a freeze-dried method was synthesized by adding samarium, leading to an increase in oxygen vacancies and high dispersion of active sites. The samarium-promoted NiMgAl catalyst showed superior catalytic activity and stability in dry and steam reforming of methane due to the scaffold structure with surface defects and oxygen vacancies, which inhibit sintering and enhance mass transportation.

Summary: This study investigates the improvement of activity and carbon deposition-resistance of hydrotalcite-derived NiMgAl catalyst for dry reforming of methane by modifying it with different loadings of zinc. Addition of zinc enhances the metal-support interaction, stabilizes smaller Ni particles, and reduces carbon nanotube growth, leading to better catalytic performance and stability. The results suggest that the increased catalyst basicity and Ni-Zn alloy formation contribute to the enhanced resistance to deactivation by coking.

Summary: NieCo/Mg(Al)O alloy catalysts with different Co/Ni molar ratios were prepared from Ni-and Co-substituted Mg-Al hydrotalcite-like compounds as precursors. These catalysts showed high activity and stability in dry reforming of methane, effectively inhibiting methane decomposition and coke deposition. Alloying Ni with Co promoted CO2 adsorption/activation and the elimination of carbon species, resulting in improved coke resistance. Hydrotalcite-derived Ni-Co/Mg(Al)O catalysts exhibited better catalytic performance compared to other Ni-Co catalysts.

Summary: Perovskite-derived catalysts in dry reforming of methane exhibit superior catalytic performance due to the synergistic effects of bimetallic addition at the B site and enhanced oxygen mobility through A site substitutions. The use of high surface area supports also greatly influences the physicochemical and catalytic behavior of perovskite-derived catalysts. The exsolution process involved in the reduction of perovskite catalysts produces smaller size metal particles which dictate the superior catalytic performance of these materials.

Summary: In recent years, there has been increased interest in dry reforming of methane to obtain syngas using CO2. Achieving high conversion rates requires working at temperatures above 1000 degrees C, but to prevent catalyst deactivation, it is convenient to work at lower temperatures. A simulated process in this work successfully recovered syngas from a dry reforming reaction at 700 degrees C, with purity and recovery rates exceeding 99%. The process also allows for the recycling of unreacted CO2 and CH4, leading to effective conversion rates close to 100%.

Summary: Promoted Ni/Y/SBA-16 catalysts exhibited enhanced catalytic performance in CO2 methanation, with the catalyst promoted with 10 wt% Y showing the best activity.

Summary: The application of layered zeolites of MWW topology in environmental catalysis, especially in selective catalytic reduction with ammonia (NH3-SCR), has been receiving increasing attention. In this study, Fe-modified NH3-SCR catalysts supported on MCM-22, MCM-36, and ITQ-2 were synthesized via a one-pot method for the first time. The results showed a correlation between the arrangement of MWW layers and the form of iron in the zeolitic structure. The one-pot synthesis resulted in high dispersion of Fe3+ sites, leading to enhanced low-temperature activity and prevention of N2O generation. Fe-modified MCM-36 exhibited the most satisfactory activity with 50% NO reduction at 150 degrees C.

Summary: In this study, the surfactant Pluronic-P123 was used for the first time to tailor NiMgAl-oxides (NMA) for CO2 methanation. The addition of P123 resulted in significant changes in the texture, morphology, and pore structure of the catalysts. The correlations between carbonate species and basic sites were identified, and the reaction mechanism involving *HCO formation as the key intermediate for CO2 methanation was proposed based on in-situ CO2 sorption measurements and Operando FTIR data.

Summary: Despite efforts to develop efficient Ti-based metal-organic framework (MOF) photocatalysts, MIL-125-NH2 remains the benchmark, and few design principles have been offered to improve photocatalytic performance. Linker functionalization in Ti MOFs has been shown to enhance photocatalysis under visible light by closing the electronic band gap and improving charge carrier lifetimes. The role of node nuclearity and topology on photocatalytic activity in known Ti-based MOFs is still unclear. Here, we report a new MOF, ICGM-1, with a 3D-connected framework featuring 1D Ti-O rods. Photocatalytic hydrogen evolution experiments reveal a significant difference in activity, solely attributed to node geometry. Time-resolved spectroscopy and DFT calculations explain these differences in terms of electronic and geometric properties, paving the way for the development of Ti-MOF photocatalysts.

Summary: This study investigated the influence of yttrium (Y) modification on the catalytic performance of nickel-based KIT-6-supported catalysts. The results showed that the addition of yttrium increased the catalyst's basicity, reduced deactivation, and improved syngas production stability. XAS-XRD analysis demonstrated that yttrium facilitated the reduction of Ni2+ to Ni-0 at lower temperatures, and the reduction rate correlated linearly with that of NiO. The effect of yttrium on the reduction rate differed for species with different interactions with the support. Furthermore, the yttrium-modified catalysts exhibited resistance to sintering of Ni particles and remained fully reduced under excess-methane dry reforming conditions.
