New Insights into Heavy Metal Sequestration Through Metal‐Phenolic Network‐Confined Nano‐HFO: Overlooking Iron Utilization and Modulating Electron Density

open access: yesAdvanced Science, EarlyView.
Iron‐based nanocomposites are widely used for trace heavy metal removal, but the low utilization of HFO nanoparticles remains a challenge. Here, a metal‐phenolic network (MPN) strategy is proposed to confine nano‐HFO within polystyrene beads, creating a negative electrostatic field and optimizing electron density at oxygen sites. This approach enhances

Unlocking Modulation Rule of Heterointerface Engineering Induced D‐Band Center on Polysulfides Conversion in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
The homologous heterostructure of ZIF‐67‐derived CoSe2@CoSe0.25S1.75 with a behavior of semi‐coherent phase boundary is constructed to modulate the d‐band center (εd) of Co, which can be a significant descriptor for Li+ storage of S cathode. It is revealed that the adsorption and conversion ability to LiPSs and the discharge‐specific capacity describe ...

Nano/Micro Metal‐Organic Framework‐Derived Porous Carbon with Rich Nitrogen Sites as Efficient Iodine Hosts for Aqueous Zinc‐Iodine Batteries

open access: yesAdvanced Science, EarlyView.
A cubic zinc‐based metal‐organic framework derived (Zn‐MOF‐derived) porous nitrogen‐doped carbon host is engineered to immobilize iodine, leveraging its hierarchical porosity and rich nitrogen sites to suppress polyiodide shuttling and enhance redox kinetics in zinc–iodine (Zn–I2) batteries.
