Summary: Pd/C catalysts are widely used in hydrogenation reactions, with Pd nanoparticles promoting H-spillover. However, in selective hydrogenation, unpromoted Pd/C catalysts are not effective. Pd single atom catalysts, although selective, have low activity. By utilizing a cooperative catalysis between Pd nanoparticles and Pd single atoms, high selectivity and activity can be achieved.

Summary: In the hydrogenation of acetophenone catalyzed by a new Pd/S-DVB catalyst, a solvent effect was found to impact the reaction efficiency. The solvent's hydrogen-bond-acceptance capacity correlates with the conversion of acetophenone, and binary mixtures of alcohol and water significantly decrease the reaction efficiency due to the microheterogeneity and blocking of the catalyst surface.

Summary: Electrolyte design is crucial for improving the performance of lithium-ion batteries. However, conventional electrolytes pose safety risks due to their flammability and reactivity at high voltage and extreme temperatures. In this study, a non-flammable fluorinated ester electrolyte was designed, which demonstrated high cycling stability and superior power capability for a graphite||LiNi0.8Co0.1Mn0.1O2 (NCM811) battery operated at high voltage (>4.3 V vs. Li/Li+) and wide temperature variations (-50 degrees C-60 degrees C). Furthermore, the research provided new insights into the molecular-level dynamics and interactions among Li+, solvent, and anion, and facilitated the development of high-safety and high-energy-density batteries for harsh conditions.

Summary: In this study, an ionic liquid-mediated method was successfully developed to construct oxygen vacancies (OVs) in defective Co3V2O8 catalyst, which exhibited excellent performance in cyclohexane oxidation. 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: We detected the presence of weak solvent-solvent interactions in electrolytes using nuclear magnetic resonance and found that these interactions play a significant role in stabilizing the electrolytes, which is a novel discovery. By studying the role of ethylene carbonate (EC) solvent in lithium-ion battery electrolyte, we found that EC can stabilize linear carbonate solvent electrolyte, particularly diethyl carbonate (DEC), through weak intermolecular interactions, enhancing the energy difference between the orbitals of the Li+(EC)(x)(DEC)(y) complex and demonstrating strong capability against reduction. Our findings were further confirmed in other metal ion batteries (e.g., Na+, K+), highlighting the importance of electrolyte design and deeper understanding of battery performance.

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.
