Summary: Barium ferrite (BaFe12O19) is a potential microwave absorption material, but the performance is limited by the poor dispersion of carbon nanotubes (CNTs) in the composites prepared by ball-milling method. In this study, CNTs were uniformly introduced into the precursor of BaFe12O19 during the auto-ignition process and calcined under different atmospheres. The resulting CNT/BaFe12O19 composites exhibited significantly improved microwave absorption performance compared to pure BaFe12O19 and CNT/BaFe12O19 composites prepared by ball-milling method.

Summary: In this study, a superhydrophobic material with a three-dimensional network frame protection was successfully constructed using metal rubber (MR) as the substrate and filling multiwalled carbon nanotubes (MWCNTs) into the pores of MR through poly(dimethylsiloxane) (PDMS) anchoring. The separation mechanism of superhydrophobic MR for emulsions was investigated, and the separation efficiency was predicted by analyzing the depth retention effect. The results demonstrated excellent purification capability and mechanical stability of the prepared superhydrophobic MR for water-in-lubricating oil emulsions.

Summary: In this study, hollow bowl-like carbon (HBC) materials were controllably constructed by the hard template method, and their tunable pore structure, surface properties, and shell thicknesses contribute to excellent performance. The HBC with a shell thickness of 3 nm exhibited the best wave-absorbing performance at a 4% absorber content. Its minimum reflection loss value was -50 dB at a thin thickness of 2.26 mm, and its effective absorption bandwidth, at a fixed thin thickness of 2 mm, could reach as wide as 7.04 GHz (10.96-18 GHz). Thin shells are essential for achieving lightweight and the bowl-like shape prevents the formation of percolative networks. with a low mass fraction of absorber content, the HBC materials can obtain moderate dielectric constant and loss, leading to good impedance matching and sufficient attenuation capacity. This work provides an effective and sustainable approach to utilize porous carbon materials for developing lightweight and high-performance wave-absorbing materials.

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.
