Copper‐based electrocatalysts effectively produce multicarbon (C2+) compounds during the electrochemical CO2 reduction (CO2RR). However, big challenges still remain because of the chemically unstable active sites. Here, cerium is used as a self‐sacrificing agent to stabilize the Cu+ of CuS, due to the facile Ce3+/Ce4+ redox. CeO2‐modified CuS nanoplates achieve high ethanol selectivity, with FE up...
With the increasing demands for novel flexible organic electronic devices, conductive polymers are now becoming the rising star for reaching such targets, which has witnessed significant breakthroughs in the fields of thermoelectric devices, solar cells, sensors, and hydrogels during the past decade due to their outstanding conductivity, solution‐processing ability, as well as tailorability. However,...
Mixed matrix membranes (MMMs), conjugating the advantages of flexible processing‐ability of polymers and high‐speed mass transfer of porous fillers, are recognized as the next‐generation high‐performance CO2 capture membranes for solving the current global climate challenge. However, controlling the crystallization of porous metal‐organic frameworks (MOFs) and thus the close stacking of MOF nanocrystals...
Gas Separation Membranes
In article number 2208177, Ming‐Jie Yin, Quan‐Fu An, and co‐workers propose a “confined swelling coupled solvent controlled crystallization” strategy to rapid preparation of mixed matrix membrane for CO2 capture. The fabricated membrane exhibits 4‐fold enhancement in CO2 permeability, benefiting from the high ZIF‐8 loading creating additional speedy mass transfer channel for...
The emergence of multidrug resistant bacteria has resulted in plenty of stubborn nosocomial infections and severely threatens human health. Developing novel bactericide and therapeutic strategy is urgently needed. Herein, mesoporous silica supported silver–bismuth nanoparticles (Ag‐Bi@SiO2 NPs) are constructed for synergistic antibacterial therapy. In vitro experiments indicate that the hyperthermia...
Electrochemical water splitting to produce hydrogen and oxygen, as an important reaction for renewable energy storage, needs highly efficient and stable catalysts. Herein, FeS2/CoS2 interface nanosheets (NSs) as efficient bifunctional electrocatalysts for overall water splitting are reported. The thickness and interface disordered structure with rich defects of FeS2/CoS2 NSs are confirmed by atomic...
A new type of hollow nanostructure featured double metal‐organic frameworks shells with metal nanoparticles (MNPs) is designed and fabricated by the methods of ship in a bottle and bottle around the ship. The nanostructure material, hereinafter denoted as Void@HKUST‐1/Pd@ZIF‐8, is confirmed by the analyses of photograph, transmission electron microscopy, scanning electron microscopy, powder X‐ray...
As a widely used nanomaterial in daily life, silver nanomaterials may cause great concern to female reproductive system as they are found to penetrate the blood–placental barrier and gain access to the ovary. However, it is largely unknown about how silver nanomaterials influence ovarian physiology and functions such as hormone production. This study performs in vitro toxicology study of silver nanomaterials,...
