Summary: An elegant method for synthesizing nanocomposites consisting of cerium-containing nanoparticles stabilized by carboxymethyl cellulose (CMC) macromolecules at room temperature was introduced in this study. The nanocomposites were characterized using microscopy, XRD, and IR spectroscopy analysis. The crystal structure of the inorganic nanoparticles, corresponding to CeO2, was determined and a mechanism for nanoparticle formation was proposed. The study demonstrated that the size and shape of the nanoparticles in the resulting nanocomposites were independent of the ratio of the initial reagents. Spherical particles with a mean diameter of 2-3 nm were obtained in different reaction mixtures with a cerium mass fraction ranging from 6.4% to 14.1%. The study also proposed a dual stabilization scheme for CeO2 nanoparticles involving carboxylate and hydroxyl groups of CMC. These findings suggest that the easily reproducible technique has promise for the large-scale development of nanoceria-containing materials.

Summary: Ag-CeO2 nanoassemblies were prepared via a simple method, with a structure comprising Ag nanoparticles and CeO2 nanoparticles. The ease of Ag-CeO2 interface oxygen activation is strongly influenced by the pyrolysis temperature. Nanoassemblies prepared at higher temperatures exhibit higher catalytic activity due to more interfacial lattice oxygen provided at lower temperatures.

Summary: This study investigates the influence of irradiation dose on the growth mechanisms and morphology of CeO2 particles formed through the radiolytic oxidation of Ce3+ in aqueous solution. The results show that different dose rates do not affect the growth pathway of CeO2 particles and result in the formation of highly ordered structures. Additionally, locally applied irradiation induces Ce-ion concentration gradients, impacting the growth of CeO2 and leading to the appearance of branched morphologies.

Summary: This study evaluated the photoactivity of CeO2 nanostructured materials in the photodegradation of CIP and proposed a possible photodegradation mechanism. CeNTs exhibited superior surface and optical properties, resulting in an increased photoactivation rate and a CIP degradation rate approximately 28% higher than CeO2.

Summary: CO self-sustaining catalytic combustion is a potential means to efficiently convert off-gases from steelmaking. Designing model catalysts is crucial for understanding the reaction process and optimizing catalysts, with Cu2O exposing (1 0 0), (1 1 1), and (1 1 0) planes being excellent materials. In this study, morphological CeO2/Cu2O inverse model catalysts were synthesized to investigate the synergistic effect and reaction mechanism. The results showed that the ignition temperature is lowered on the interface due to the synergistic effect, while the combustion after ignition is controlled by Cu2O planes providing lattice oxygen for CO reaction. Additionally, the exposure of different planes plays a significant role in the reaction process, with O-termination on (1 0 0) inhibiting the interaction, Cu-termination on (1 1 0) surface structure, and coordinately unsaturated Cu+ on open (1 1 1) surface contributing to superior catalytic performance.

The results showed that ruthenium-containing catalysts exhibited higher activity, and the Ir-Ru 1:3 sample showed higher activity and less degradation after the procedure. Chemical and structural analysis revealed that the stability of the Ir-Ru 1:3 sample was related to the RuO2 chemical state and hcp structure.

Summary: Single-atom catalysts are important heterogeneous catalysts. Recent studies show that single-atom sites on the catalyst substrates can significantly affect the distribution of metal nanoparticles. By controlling the atmosphere, researchers can control the size of Pt nanoparticles on ceria-based single-atom catalysts, leading to changes in catalyst activity and stability. The competition between Pt single-atom sites and Pt nanoparticles determines the morphology of Pt nanoparticle population on the ceria surface. In oxidizing atmosphere, Pt single-atom sites bond strongly with Pt atoms and cause nanoparticle shrinkage, while in reducing atmosphere, Pt single-atom sites are emptied and Pt nanoparticles grow. A generic model of Pt redispersion and coarsening on ceria substrates is proposed, providing an atomic-level explanation for various dynamic processes observed in single-atom catalysts.

Summary: The adsorption of phenylphosphonic acid (PPA) on Cu(111) was studied and it was found that the dehydrogenated phenylphosphonic acid molecule (PP) is the dominant surface species in the temperature range 150-300 degrees C. The stable PP adlayer effectively protects the Cu(111) surface from oxidation. Furthermore, thermal treatment of the PPA adlayer leads to molecular decomposition and subsequent formation of phosphorus-rich species at higher temperatures.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
