Summary: The novel Fe3O4@MoS2 composite exhibited enhanced piezo-catalytic degradation of rhodamine B and good magnetic recovery/recycling features. It was found that the composite could efficiently adsorb rhodamine B in solution, and piezo-electrons, holes, and superoxide anions played key roles in the degradation process of rhodamine B. The study provides new insights into the working mechanisms and process profiles of composite piezo-catalysts beyond the development of a high-performance MoS2-based piezo-catalyst.

Summary: Electromagnetic pollution affects health and equipment, but a flower-like (MoS2/Fe3O4)@rGO nanocomposite with strong EMW absorption property was synthesized. The combination of Fe3O4, rGO, and MoS2 improved the composite's electromagnetic parameters and impedance matching. The composite achieved a minimum reflection loss of up to -64.05 dB at 1.83 mm and an effective absorption bandwidth of 7.34 GHz at 2.5 mm, attributed to the synergistic effect of different loss mechanisms and the magnetic loss induced by Fe3O4.

Summary: Water pollution can be treated through the photocatalytic reaction of TiO2 or TiO2 compounds. In this study, Fe3O4 and Fe3O4@TiO2 composite photocatalysts were prepared using a solvothermal method, and it was found that Fe3O4@TiO2 can reduce the band gap and maintain a certain proportion of high-energy facet exposure. The photocatalytic degradation experiment demonstrated that Fe3O4@TiO2 can significantly improve the degradation efficiency of Acid Red 73 and achieve higher degradation rate after self-cleaning treatment.

Summary: In this study, molybdenum disulfide (MoS2) nanoparticles were obtained through liquid phase exfoliation with the presence of chitosan, and then melt mixed with linear low-density polyethylene (LLDPE) to produce novel antimicrobial active packaging materials. These nanoparticles formed aggregates that were well dispersed in the polymer matrix, providing several functionalities to the LLDPE, including antimicrobial behavior and changes in surface properties. Despite significantly increasing water vapor permeation, MoS2 showed a decrease in oxygen permeation. The nanocomposites exhibited promising potential for the development of antibacterial active packaging films without compromising the mechanical properties of the pure LLDPE matrix.

Summary: In this work, N-doped BiOBr nanosheets were prepared by using a high-shear mixer followed by a hydrothermal method to evaluate the effect of N incorporation in BiOBr on photocatalytic degradation of organic contaminants. The N-doped BiOBr photocatalysts showed significant improvement in photoreactivity for degrading organic contaminants in wastewater compared to undoped BiOBr. The 0.9N-BiOBr exhibited the highest photocatalytic degradation performance under visible-light irradiation, with a 15.3 times higher degradation rate than undoped BiOBr. The results demonstrate that N doping can enhance the photodegradation performance of BiOBr-based photocatalysts.

Summary: In this study, TiO2/CdS nanocomposites with different exposed facets were synthesized and characterized. Among them, FMA-TiO2/CdS exhibited the highest photocatalytic activity with a degradation efficiency of 88.4%, attributed to its largest surface energy, co-exposed {101}/{010} facets, lowest photoluminescence intensity, lower charge-transfer resistance, and higher charge-transfer efficiency.

Summary: To simplify the synthesis of interlayer-expanded MoS2 (E-MoS2), a reactant conversion-intercalation strategy is developed using ammonium thiocyanate as the intercalator. The obtained E-MoS2 exhibits superior supercapacitor performance with high specific capacity and energy density. The favorable electrochemical performance is attributed to the expanded interlayer spacing and the large Na+ adsorption capacitance. This work provides a novel intercalation strategy for the development of high-performance electrode materials for energy applications.

Summary: Three types of a-Mn2O3 catalysts with different morphologies were prepared and evaluated for ethanol total oxidation. The a-Mn2O3-cubic catalyst showed a higher reaction rate than the other two types under high space velocity. The morphology-dependent reactivity was found to be correlated with low-temperature reducibility, surface Mn4+ abundance, and adsorbed reactive oxygen species.
