Summary: This study evaluated the properties of a composite solid electrolyte (CSE) prepared by adjusting the particle size of an active filler, Li6.4La3Zr1.4Ta0.6O12 (LLZTO), which resulted in higher lithium ionic conductivity when compared to the original LLZTO CSE. The use of small particle size in the BM-LLZTO CSE allowed for fast lithium-ion transport pathways, as confirmed by NMR analysis. The BM-LLZTO CSE showed lower overvoltage and better performance in Li-ion cells compared to the LLZTO CSE.

Summary: Incorporating inorganic fillers into composite polymer electrolytes (CPEs) is a common strategy to enhance ionic conductivity. However, poor interfacial contact between inorganic fillers and polymer chains is often encountered. In this study, a surface positive-charge modification strategy was developed to improve the intermolecular interaction of poly(ethylene oxide) (PEO) electrolytes with inorganic fillers and optimize lithium ion conductive pathways in CPEs. The modified fillers not only induce more amorphous structure into the PEO matrix but also promote the dissociation of lithium salts, resulting in enhanced Li ion transport.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
