Summary: This work demonstrates the preparation of nitrogen doped carbon immobilized Pd single atom catalysts (SACs) with high loading through co-axial emulsion electrospinning and CO2 thermal activating method. The resulting Pd SACs carbon fibers have a bamboo-like tubular structure with multiscale pores, allowing easy access to the active sites. These multiscale porous hollow Pd SACs exhibit excellent activity and selectivity for phenylacetylene semi-hydrogenation. Moreover, this universal method can be applied for the preparation of other 1D metal SACs, offering great potential in the development of easily available and efficient SACs.

Summary: In this study, a series of Pd@PC-COFs catalysts were prepared using different solvents for wet impregnation. The choice of impregnation solvent had a significant impact on the microstructures, surface characteristics, and catalytic properties of Pd@PC-COFs catalysts for selective phenol hydrogenation. The Pd@PC-COF-NBA catalyst exhibited the highest catalytic activity and superior performance due to its larger specific surface area, well-developed pore structures, higher Pd content, improved Pd dispersion, and other factors. Pd@PC-COF-EA and Pd@PCCOF-Dio showed good catalytic stability over five reaction cycles. These findings contribute to the development of high-performance Pd@COFs for selective phenol hydrogenation.

Summary: A heterogeneous Pd-NPMO hybrid-silica catalyst was synthesized and utilized for selective hydrogenation of phenol to cyclohexanone in aqueous phase at near ambient temperature and atmospheric hydrogen pressure. The Pd nanoparticles homogeneously distributed on N-bridged hybrid mesoporous organosilica exhibited higher activity and selectivity compared to the unmodified Pd-SBA-15 catalyst. Control experiments confirmed the role of nitrogen domains in the hybrid silica support in stabilizing small Pd nanoparticles and modifying the Pd sites responsible for catalysis in water. The stable and reusable nature of the bifunctional Pd catalyst demonstrated its heterogeneity.

Summary: Size-controlled Pd nanoparticles were successfully synthesized in the pores of mesoporous silica nanoparticles, showing higher catalytic activity in the Suzuki-Miyaura cross-coupling and hydrogenation reactions compared to larger nanoparticles. The enhanced activity can be attributed to the increased number of coordinatively unsaturated sites and higher back donation capacity of the smaller nanoparticles.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
