Summary: This study developed dual-layer hollow fiber (DLHF) membranes with dual functions of biocompatible adsorption and antibacterial effects to solve the problem of incompatible membranes and bacterial endotoxin contamination. DLHF membranes with silica/ a-mangostin nanoparticle in the inner layer and activated carbon (AC) in the outer layer showed improved antibacterial properties, urea and creatinine removal capabilities compared to single-layer membranes. The co-adsorptive biocompatible DLHF membrane can play an important role in improving the lives of kidney patients.

Summary: We develop hollow porous silicon nanospheres with a three-dimensional carbon coating and SiC transition interlayer (C@SiC@Si@SiC@C) to address the challenges faced by Si anodes. The synthesized C@SiC@Si@SiC@C anode shows high utilization of the active substance, high measured capacity (3200 mAh g-1), and stable cycling performance (0.7% per cycle decay rate at 0.2C). The superior performances are attributed to the unique structure design and the functional features of carbon coating and SiC transition interlayer.

Summary: In this study, mesoporous ZnCoSiOx hollow nanoreactors with different metal distributions and microenvironment were designed based on the diffusion behavior of metal species in confined nanospace. By using core@shell structured ZnCo-zeolitic imidazolate framework (ZIF)@SiO2 as a template and employing different synthesis methods, double-shelled hollow structures with well-distributed metal species and yolk@shell structures with a collective (Zn-Co) metal oxide as the yolk were successfully obtained. The catalytic performance of these nanoreactors in CO2 hydrogenation showed that the dispersion and location of active sites in the catalysts play a crucial role in determining the main products.

Summary: This study synthesized a series of edge-enriched N, S co-doped carbon materials by pyrolysis of thiourea encapsulated in zeolitic imidazolate frameworks. These materials exhibited excellent oxygen reduction reaction (ORR) performance in alkaline medium, with low onset potential, good stability, and methanol tolerance. Density functional theory (DFT) calculations revealed that the carbon atoms adjacent to N and S are the probable active sites for ORR intermediates in the edge-enriched N, S co-doped carbon materials, due to their higher electron density, which enhances O2 adsorption and lowers the formation barriers of intermediates, thereby improving the ORR performance.

Summary: The influence of crystal phase on the electrocatalytic performance and active sites of CuFe2O4 spinel for the electrochemical dechlorination of 1,2-dichloroethane is studied. A higher activity and ethylene selectivity are observed for the cubic phase compared to the tetragonal phase, indicating the significant enhancement of electrocatalytic performance by the cubic crystal structure. The octahedral Fe atom on the surface of cubic CuFe2O4(311) is identified as the active site responsible for ethylene production with an energy barrier of 0.40 eV. This work highlights the importance of crystal phase engineering for optimizing electrocatalytic performance and provides an efficient strategy for the development of advanced electrocatalysts.

Summary: Nano-sized SSZ-13 with hierarchical structure was synthesized by combining ultrasonic pretreatment and seed induced crystallization. The synthesized catalysts were characterized by various techniques, and it was found that ultrasonic pretreatment reduced the crystallization time and decreased the zeolite crystals to nano size. The hierarchical nano-sized SN-17 catalyst showed improved catalytic lifetime and selectivity for ethylene and propylene due to enhanced mass transport efficiency and decreased coking rate, compared to the conventional SM-24 catalyst.

Summary: The article explores the importance of mass transfer in catalytic processes, specifically in the electrocatalytic oxygen reduction reaction (ORR) by tailoring the pore sizes. By employing a confined-etching strategy, boron-and nitrogen-doped carbon (B,N@C) electrocatalysts with abundant active sites but different porous structures were fabricated. The ORR performance was found to be correlated with reactant diffusion, with the optimized B,N@C catalysts featuring trimodal-porous structures demonstrating enhanced O2 diffusion and improved activity per heteroatomic site. The study highlights the significance of nanoarchitecture engineering in catalysts and provides insights into optimizing structures with abundant active sites and enhanced mass transfer.

Summary: Engineering the surface structure of semiconductor is a promising strategy for improving charge separation and transfer efficiency in photocatalysis. In this study, C decorated hollow TiO2 photocatalysts (C-TiO2) were designed and fabricated. The optimal C content and Ti-O-C bonds in C-TiO2 were found to enhance light absorption and promote charge separation and transfer, leading to a 5.5-fold higher activity in H2 evolution compared to TiO2. This work provides a feasible strategy for rational design and construction of surface-engineered hollow photocatalysts to enhance photocatalytic performance.

Summary: In this study, a water-conducting LTA membrane with well-distributed non-penetrative macroholes was prepared, resulting in a cheese-like structure that combines the advantages of micro-nanochannels for high water selective permeability and macroholes for quick water diffusion. The optimized SH-LTA membranes showed high water permeability and good stability, with permeances of methanol, H2, and CO2. The dissolution-recrystallization route of the SH morphology was confirmed, and molecular dynamics simulations were used to elucidate the superior water separation behavior in the SH-LTA membrane compared to the pristine LTA membrane.
