Summary: Yttrium promotion in Ni/Mg/Al double-layered hydroxides leads to improved reducibility of Ni species and total basicity, resulting in higher CH4 and CO2 conversions in dry reforming of methane. However, this also leads to significant carbon deposits, with NiY8-DLH showing the best catalytic stability.

Summary: A series of mono and bimetallic catalysts based on Ni, Rh, and Pd supported on different materials were evaluated for the dry reforming of methane reaction. Ni-based catalysts suffered from deactivation but could be regenerated, while Pd-based catalysts deactivated due to coke deposition. Rh-based catalysts showed remarkable activity and stability.

Summary: This study investigated the application of K-promoted Ni/MgAl2O4 catalysts with different K/Ni ratios in dry reforming of methane to improve the utilization of CO2 and CH4. The promotion of nickel catalysts with potassium was found to affect nickel distribution, metal-support interactions, and carbon deposition, leading to enhanced CO2 adsorption and reduction of the H-2:CO ratio of the catalysts.

Summary: Unlike the traditional steam reforming process, the dry reforming of methane directly utilizes CO2 to produce syngas. Catalyst deactivation caused by carbon deposition has hindered the industrialization of this process. However, this study provides evidence that carbon deposits on the catalyst surface are actually an intermediate product formed during the DRM reaction and can be removed by reaction with CO2. The presence and nature of carbon deposits have important implications for optimizing DRM reaction conditions and improving yields.

Summary: Increasing the calcination temperature of nickel-based catalysts on alumina leads to the formation of nickel-alumina spinel, enhancing metal-support interaction and reducing temperature. It also decreases nickel nanoparticle size and increases effective dispersion due to the formation of nickel aluminate. The catalyst calcined at 750 degrees C shows the highest conversion rates in methane dry reforming and excellent stability in a 200 h test.

Summary: In this study, nickel- and iron-modified titanium dioxide (Ni-Fe/TiO2) catalysts were investigated for the dry reforming of methane (DRM) at 550 degrees C. The addition of Fe was found to decrease the conversion of both CO2 and CH4, and XPS results showed changes in the surface nickel and iron species. Characterization techniques, including TGA and Raman spectroscopy, indicated that Fe addition greatly inhibited coke formation and in situ DRIFTS confirmed the formation of carbonate species, which aided in the removal of deposited coke.

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: The dry reforming of methane (DRM) was studied using Ni-based catalysts promoted with various amounts of gadolinium oxide. The addition of 4.0 wt.% gadolinium resulted in the best catalyst performance, with around 80% and 86% conversions of CH4 and CO2, respectively. The gadolinium oxide improved the catalyst basicity and interaction with the support, leading to higher coke resistance and stability.

Summary: This research focuses on a Ni-Mg-Al hydrotalcite-derived catalyst promoted with Cu for CO2 hydrogenation to methane. The Cu promotion was especially effective at low temperatures, leading to significant CO2 conversion and selectivity for methane formation. Higher Cu content did not necessarily result in better activity, as high Cu concentrations were found not to be suitable for CO2 methanation. Additionally, the formation of Ni-Cu solid solution and subsequent redispersion of Ni-Cu alloy during the methanation reaction were observed.

Summary: The catalytic performance of Fe-MCM-22 catalysts with different Si/Fe molar ratios in NH3-SCR was investigated. It was found that the sample with the lowest Fe concentration exhibited the highest catalytic activity due to the abundance of well-dispersed isolated iron species. The decrease of Si/Fe limited the formation of microporous structure and resulted in partial amorphization, formation of iron oxide clusters, and emission of N2O during the catalytic reaction.

Summary: In this study, clinoptilolite-supported catalysts modified with hydrotalcite-like phase were investigated for NH3-SCR reactions. The results showed that the deposition of hydrotalcite on the catalyst surface enhanced the conversion of NO within a specific temperature range. The promoting effect was attributed to the presence of Bronsted acid sites and the ability to adsorb and accumulate ammonia. Furthermore, the thermal decomposition of hydrotalcite during the catalytic reaction generated Fe sites of higher nuclearity, eliminating the need for pre-calcination.

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.
