Summary: A multi-layered nanostructured Ni/CeO2 catalyst was synthesized and its catalytic activity was improved through pre-treatment. The catalyst showed stable conversions of CO2 and CH4 and a high H2/CO ratio, which can be attributed to the multi-layered structure, enhanced metal-support interface, and formation of carbon and oxygen species on the catalyst surface.

Summary: The strong bonding between the metal and support known as strong metal-support interaction (SMSI) can inhibit the aggregation of metal nanoparticles and carbon deposition during hydrocarbon reforming. This interaction is significantly affected by the heat treatment and reducing conditions during catalyst preparation. A mild reduction process using dry methane gas is proposed to increase the exposed interface between the metal and support and enhance the catalytic activity of the nanocatalyst. The effects of this process on the chemical state of Ni-cerium oxide nanocatalysts were investigated, leading to the formation of a significant amount of the Ni3+ phase and improved SMSI.

Summary: A surface spatial confinement strategy using dendritic layered gamma-Al2O3 (DL-Al2O3) was employed to design a stable Ni-based catalyst for dry reforming of methane (DRM). The Ni nanoparticles were separated and confined by the gamma-Al2O3 layers, ensuring the superior activity and stability of Ni/DL-Al2O3. Furthermore, the reversible phase change of NiAl2O4 and Ni/Al2O3 derived from nanosheet gamma-Al2O3 enabled catalyst regeneration and recovery of catalytic activity of Ni/DL-Al2O3.

Summary: Phosphorus pollution can cause both aquatic eutrophication and global phosphorus scarcity. Fe-based layered double hydroxides (LDHs) have been extensively studied for their high phosphorus adsorption and recovery. The composition of Fe-based LDHs is crucial in determining their adsorption performance. In this study, Zn/Fe LDH exhibited a much higher adsorption capacity than Mg/Fe LDH, and calcination significantly increased the adsorption capacity of Mg/Fe LDH. The phosphorus removal efficiency of Fe-based LDHs was high under acidic conditions but decreased with increasing pH, with Zn/Fe LDH showing weaker pH inhibition.

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: 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.
