Summary: Biologically inspired adhesives microstructure with both flexibility and rigidity is a challenge. To tackle this, a honeycomb structure with a soft elastic film has been fabricated, providing support and flexibility for a strong attachment. The resemblance to octopi's sucker generates suction forces. Experimental results and theoretical prediction demonstrate the synergistic role of van der Waals and suction forces in this partial-film honeycomb microstructure, making it a stronger and surface adaptable adhesive. The critical role of viscous forces in water and silicon oil wetting conditions is also investigated.

Summary: The study revealed that the NH3-SCR activity of Nb2O5-CeO2 and WO3-CeO2 catalysts depends significantly on the strong interaction between the redox component (CeO2) and acidic component (Nb2O5 or WO3), as well as the presence of paired redox-acid sites. At lower temperatures (200 degrees Celsius), NH3-SCR activity is primarily influenced by the surface acidity of the catalysts, while at higher NOx conversion rates, the activity is more determined by the redox properties.

Summary: The study focuses on the improvement of Pt-CeO2 catalysts by designing new ceria-based supports. Through a unique T-IWI method, a Pt single site catalyst with excellent thermal stability was synthesized on a CZA-T support. The catalyst showed higher oxidation activity and Oxygen storage capacity (OSC) compared to traditional Pt catalysts on regular CeO2/Al2O3 and one-step prepared CeZrOx/Al2O3 supports. The higher Pt dispersion and stronger Pt-O-Ce interaction on the CZA-T support played a vital role in the CO oxidation performance and OSC of the catalyst.

Summary: In this study, an efficient NbCuCe oxide catalyst for reducing NOx emissions in cold-start diesel engines is reported. The catalyst exhibits higher DeNO(x) activity below 200 degrees C compared to the Cu-CHA zeolite catalyst, along with superior sulfur resistance, faster response, and lower NH3 slip. Atomically dispersed Cu species facilitate strong interaction between Cu and the Nb/Ce base catalyst, leading to improved low-temperature redox properties and NH3 adsorption/activation. The developed NbCuCe catalyst shows promising potential for efficient DeNO(x) in cold-start diesel engines and can be combined with Cu-CHA for a broader temperature range of operation.

Summary: In this study, an efficient CuO catalyst supported on a CeO2-Al2O3 support (CA-T) prepared by two-step incipient wetness impregnation (T-IWI) method was successfully developed. The Cu/CA-T catalyst exhibited better catalytic performance in CO oxidation and NO reduction by CO (NO + CO reaction) as well as higher thermal stability compared to the CuO catalyst loaded on conventional CeO2-Al2O3 support (Cu/CA). The microstructure of CuO-CeO2-Al2O3 catalysts, especially the state of Cu species, was systematically investigated using various characterization techniques. The mechanisms of CO oxidation and NO + CO reactions on Cu/CA and Cu/CA-T catalysts were collaboratively revealed.

Summary: The size effect on nanoparticles plays a crucial role in catalysis performance. Tuning the oxygen vacancies on a metal-oxide support can help reduce the size of Pt particles, thus improving the catalysis performance of the supported catalyst. In this study, Ce-Sn solid solutions (CSO) with abundant oxygen vacancies were synthesized. After CO reduction, the catalytic CO oxidation performance of Pt/CSO was significantly better than that of Pt/CeO2. This improvement was attributed to the creation of smaller Pt clusters on CSO with more exposed active sites.
