Summary: We have successfully prepared hybrid nanoparticles by coaggregating urushi, a form of black oriental lacquer, and lignin as natural components. Urushi acts as a sustainable component that stabilizes the particles through hydration barrier effect and thermally triggered internal cross-linking. The weight fractions of the two components can be adjusted to achieve the desired level of stabilization. Hybrid particles with Urushi content >25 wt% undergo interparticle cross-linking, producing multifunctional hydrophobic protective coatings that improve the water resistance of wood. This approach provides a sustainable and efficient method for stabilizing lignin nanoparticles and opens up new possibilities for the development of lignin-based advanced functional materials.

Summary: This study investigated the alkylation performance of X zeolites with different particle sizes in a continuous-flow slurry reactor. The results showed that larger particle size can enhance catalyst stability, while smaller particle size is favorable for product diffusion. However, significant dealumination and structural defects can occur in smaller particles, impacting their acidity and overall alkylation performance. Thus, an optimal particle size range is speculated for the use of X zeolites in a slurry reactor for alkylation.

The ionic liquids not only acted as structure-directing agents but also promoted the formation of OVs through coordination with Co2+ and V5+, accelerating the redox cycle and enhancing substrate activation and electron transfer. This design presents a facile strategy for constructing OVs using ionic liquids and provides insights into OV-rich mixed metal oxides in selective oxidation.

Summary: A series of CHR-VOx were prepared by controllable hydrogen treatment and reduced to states dominated by V5+ and V4+ species. The catalytic roles of V-species and O-species for cyclohexane oxidation were explored. The surface properties of CHR-VOx underwent remarkable changes, leading to significant improvement in catalytic performance. XPS and Raman confirmed the reduction behavior. Moderate-reduced CHR-VOx with 78.7% multi-liganded-oxygen (O-L) showed the best conversion for cyclohexane (11.8%), while over-reduced CHR-VOx with a large content of V4+ species (33%) exhibited the best selectivity for adipic acid (44.3%). O-L sites were identified as the active sites for cyclohexane activation, while V4+ species were regarded as oxygen vacancies (OVs) contributing to further oxidation to adipic acid.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
