Summary: Platinum nanoparticles supported by titania can form overlayer due to strong metal-support interaction, which can enhance the catalyst's properties and prevent sintering. The overlayer can be reversed through oxidative treatments, but recent findings suggest its stability in oxygen. In our study, we used in situ transmission electron microscopy to investigate the changes in the overlayer under different conditions and found that high temperature and oxygen atmosphere preserved the overlayer, preventing platinum evaporation.

Summary: The study reveals that during the catalytic conversion of 2-propanol on Pd/TiO2 at low temperatures, coverage of Pd sites occurs due to the generation of SMSIs. The SMSIs that appear during the reaction fully reverse upon exposure to O-2 at room temperature, which may have contributed to the challenge of identifying them in the past.

Summary: This study systematically investigates a series of nickel-iron-based bimetallic catalysts to unveil the nature of active sites for the CO2 hydrogenation reaction, revealing an environmental-sensitive strong metal-support interaction between Ni nanoparticles and iron oxides. Iron oxides migrate and entirely cover the metallic Ni nanoparticles during the reaction, yielding a more active core-shell-type structure with much-improved reducibility, a process indirectly monitored in a time-resolved manner by in situ DRIFTS and confirmed to complete within 30 min of the reaction.

Summary: In this study, the strong metal-support interaction (SMSI) phenomenon for supported Ni/CeO2 catalysts with different CeO2 nanomorphologies was systematically explored. The degree of encapsulation of Ni particles originating from the SMSI effect was found to be positively correlated with the CO2 hydrogenation activity. Quasi in situ XPS and in situ DRIFTS techniques were used to reveal the relevant species and reaction pathways. These findings provide a fundamental strategy for tailoring catalytic performance by adjusting the support surface structure.

Summary: A new form of strong metal-support interaction (SMSI) has been achieved by creating oxygen-saturated overlayers on Au/TiO2 catalyst through steaming treatment, which demonstrates improved stability compared to classical SMSI. The study shows that the strong interaction between the TiOxHy (x ≥ 2) species and Au surface causes the migration of TiO2 to encapsulate Au nanoparticles. The oxygen-saturated oxide overlayers exhibit stability in oxidative, reductive, and humid atmospheres, providing enhanced performance for metal nanoparticle catalysts under various reaction conditions, surpassing classical SMSI.

Summary: Although zinc oxide is widely used in organic solar cells, its light-soaking issues can lead to reversible degradation and incorrect stability measurements. The re-adsorption of oxygen trapped at the interface of ZnO causes this reversible aging, which can be undone with a UV exposure. However, this UV pretreatment compromises device efficiency and production in an oxygen-free environment.

Summary: Researchers have discovered that the sorption and conversion of gaseous molecules on the surface of functional materials preferentially occur on specific undercoordinated high-index surface sites. By combining in situ PiFM with DFT calculations, they have studied the site-specific sorption and conversion of formaldehyde on faceted ZIF-8 microcrystals and observed preferential adsorption on high-index planes. They have also visualized unsaturated nanodomains and found structure sensitive conversion mediated by Lewis acidity on defective ZIF-8 crystals.

Summary: The growth mechanisms and molecular phenomena of UiO-67, UU-1, and ZIF-8 metal-organic framework (MOF) films on transparent substrates are studied using transmission-based characterization. UiO-67 follows a Volmer-Weber growth mechanism with assistance from solution-grown seeds. UU-1 exhibits fiber-like morphology and inter-fiber macroporosity, while ZIF-8 shows a similar Volmer-Weber growth mode. CO probe molecule adsorption FT-IR spectroscopy reveals the effects of methanol exposure, with UiO-67 becoming inaccessible to CO, UU-1 undergoing a topotactic transformation, and ZIF-8 remaining stable with impurity removal. This approach opens new possibilities for studying other film materials using transmission-based spectroscopy.

Summary: Interfaces in III-V semiconductor devices are usually buried and difficult to characterize. However, the Tapered Cross Section Photoelectron Spectroscopy (TCS-PES) approach provides a promising method to address this challenge. In this study, the TCS-PES was used to investigate the heterojunction in epitaxial III-V architectures prepared by metalorganic chemical vapor deposition. The results showed that the preparation of TCSs under an uncontrolled atmosphere led to the modification of the pristine properties of buried heterointerfaces.

Summary: The maritime sector accounts for a significant amount of global greenhouse gas emissions and is facing pressure to decarbonise. Renewable fuels show potential, but their high costs are a barrier. Carbon Capture and Storage (CCS) can enhance marine fuel decarbonisation, but adds to the cost. This study compares the costs of four renewable carbon fuels and considers the impact of carbon taxation. The results show that without carbon taxation, renewable fuels are not competitive, and methanol and DME produced using CO2 capture are the most cost-effective options.

Summary: Lignin partial depolymerization by reduction (PDR) is a strategy to modify the molar mass and heterogeneity of technical lignin, and increase its reactivity in polymer applications. The process aims to break the remaining lignin beta-O-4 linkages, reducing the molar mass of large lignin fragments. The PDR process provides control over key lignin characteristics, allowing for tailored biobased polymer properties.

Summary: This study reveals that the presence of a catalytically inactive siliceous exterior rim on ZSM-5 particles can significantly reduce diffusion limitations, leading to an improved catalyst lifetime. The synthesis of Si-zoned ZSM-5 catalysts improves the diffusion properties of the catalyst. Operando ultraviolet-visible light diffuse reflectance spectroscopy shows a substantial reduction in external coking among Si-zoned samples. Molecular dynamics simulations demonstrate that there are significantly reduced transport limitations in the zoned regions, which contributes to the improved catalyst activity of Si-zoned zeolites compared to ZSM-5 with a homogeneous acid-site distribution.

Summary: Understanding and controlling the structure and composition of nanoparticles in supported metal catalysts are crucial for improving chemical processes. Atom probe tomography (APT) is a powerful tool for three-dimensional chemical imaging of materials with nanometer resolution. However, APT has not been used for mesoporous oxide-supported metal catalysts due to sample fracture. In this study, we developed a high-pressure resin impregnation strategy to overcome this issue and successfully applied APT to high-porous supported Pd-Ni catalyst materials active in CO2 hydrogenation. Our results demonstrate the capability of APT to quantitatively assess the size, composition, and metal distribution of nanoparticles in industrial catalysts.

Summary: A series of silicon oxycarbide ceramics with different carbon content were prepared by thermal pyrolysis and spark plasma sintering. The high carbon content resulted in a porous microstructure, and the sample with 40 wt% carbon content exhibited a porosity of 34% and a specific surface area of 262 m(2)/g at 1600 degrees C. The electrochemical behavior of SiOC was evaluated and showed certain electrocatalytic activity, with the sample containing 10 wt% carbon showing an overpotential of 450 mV vs. RHE at 10 mA.cm(-2) in acid medium. The electrochemical behavior was found to be closely related to the phase composition and microstructure of the ceramics.

Summary: Diels-Alder cycloaddition is an important transformation in chemistry, especially in the synthesis of versatile bio-based platform molecules. However, the reactivity of common furanic compounds presents a major challenge for industrial applications. In this study, we report a highly efficient intramolecular Diels-Alder reaction between allyl acetals of different furfurals, resulting in the formation of oxanorbornene derivatives with high chemo-, regio-, and stereoselectivity. These derivatives can be easily diversified into valuable products, offering potential for scalable production of renewable chemical building blocks from inexpensive bioderived platform molecules.
