Summary: The study presents a series of nanocatalysts derived from immobilization of palladium nanoparticles (Pd NPs) into the 3D tube-type architecture of nitrogen (N) functionalized and without functionalized mesoporous carbon CMK-9 by a dual agents chemical reduction approach. The Pd@N-CMK-9 catalysts exhibit excellent catalytic activities in Suzuki-Miyaura cross-coupling reaction, reduction of 4-nitrophenol, and hydrodechlorination of chlorobenzene, showing 100% conversion rates and high turnover frequencies. The outstanding catalytic performance is attributed to the synergistic effect of uniformly dispersed Pd NPs, favorable metal-support interaction, and tubular interconnected mesoporous framework of N-functionalized CMK-9.

Summary: Ni catalysts decorated with trace Rh supported on gamma-Al2O3 were prepared and investigated for the catalytic hydrodechlorination of chlorinated hydrocarbons. The introduction of Rh facilitated the generation of spillover hydrogen, enhancing the H2 activation ability of the Ni catalyst. The bimetallic Ni-Rh/gamma-Al2O3 catalyst exhibited significantly higher 1,2-dichloroethane conversion (37%) and comparable selectivity to ethylene (95%) compared to the monometallic Ni catalyst.

Summary: Hydrodechlorination (HDC) via heterogeneous catalysis using liquid hydrogen donors is an effective method for degrading and removing chlorophenols. In this study, Pd and Pd-M (M=Zn, Ni, Co) catalysts supported on commercial multiwall carbon nanotubes (MWCNTs) and N-doped MWCNTs (N-MWCNTs) were used to investigate their catalytic performances for the HDC of 2-chlorophenol (2-CP) using methanol as the hydrogen donor. The results showed that N-doping and/or the addition of a second metal effectively increased the catalytic activity of the Pd catalysts, achieving nearly 100% conversion of 2-CP using Pd-Zn/N-MWCNTs. Characterization techniques were employed to better understand the reaction mechanism and the effects of N-doping and the addition of a second transition metal to the catalyst.

Summary: The composite material Pd/Fh, consisting of Pd nanoparticles supported onto mesoporous ferrihydrite, demonstrates excellent catalytic dehalogenation performance with rapid and complete removal of chlorophenol. The unique functions of Fh, including providing interaction sites with metals, facilitating adsorption of chlorophenol, and acting as an electron mediator, contribute to the synergistic effect between Pd catalyst and the support, enhancing dechlorination activity. This work presents a promising catalyst for efficient dehalogenation of chlorinated environmental pollutants and provides insights into the relationship between catalyst structure and dehalogenation activity.

Summary: This study investigates the upgrading of wasted chloroform for the production of olefins using different catalysts prepared with different precursors. The results show that PdCl-based catalysts demonstrate electron transfer from the support to Pd nanoparticles, which is not observed in PdN-based catalysts. The catalyst with the smallest and well-dispersed Pd nanoparticles on CNT exhibits the highest activity and selectivity to olefins, while the other catalysts suffer from lower selectivity and activity due to the formation of Pd carbides on larger Pd nanoparticles.

Summary: In this study, a Pd nanoparticles catalyst supported on hexagonal boron nitride (h-BN) was developed for the hydrogenation of aldehydes/ketones to alcohols via hydrogen spillover. The feasibility of hydrogen spillover from Pd to h-BN is determined by the nitrogen vacancies in h-BN. The hydrogen spillover-based hydrogenation mechanism leads to a high tolerance to CO poisoning for the catalyst system.

Summary: In this study, a Fe-doped NiO nanoarray interlayer-modified Pd/Ni foam (Pd/Fe-NiO/NF) was synthesized as an efficient cathode catalyst for electrocatalytic hydrodechlorination (ECH) of 2,4-dichlorophenoxyacetic acid (2,4-D). The Fe-NiO nanoarray on the nickel foam increased the electrochemically active surface area of the electrode and improved the dispersion of catalytically active Pd nanoparticles (Pd NPs). Introducing the Fe-NiO interlayer facilitated water ionization and atomic H* generation, providing more atomic H* for the ECH process. Compared to the conventional Pd/NF electrode, the Pd/Fe-NiO/NF showed enhanced dechlorination efficiency and reduced Pd requirement, with excellent reusability and stability.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
