Three‐Step Pulse Strategy Enhances Ultradilute Nitrate‐to‐Ammonia Conversion via Microenvironment and Mass Transfer Control

open access: yesAdvanced Science, EarlyView.
Electrochemical treatment of low‐concentration nitrate in wastewater is challenging. This study introduces a three‐step pulsed method that achieves near‐perfect efficiency in converting ultradilute nitrate to ammonia. Combined experiments and simulations reveal how pulsed strategy boost kinetics while suppressing competing reactions.

Engineering Separated Dual O2 Reduction Cores into One Polymer Framework for Boosting Hydrogen Peroxide Production

open access: yesAdvanced Science, EarlyView.
Here the rational design of two O2 reduction cores into one polymer framework is showcased for synergistically facilitating H2O2 production via the “selfmarketing & cooperation” strategy. Photoactive units of pyrrolo[3,2‐b]pyrrole and porphyrin are successfully settled in covalent organic polymers (COPs) through polycyclizations of the relevant ...

Slide‐Crosslinked Polyrotaxane Topological Networks: Quasi‐Solid Electrolyte for High‐Voltage Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A series of sliding crosslinked quasi‐solid electrolyte (PMBA‐PPRx) is designed for high‐voltage lithium metal batteries, concurrently addressing the critical bottlenecks of conventional polymer electrolytes: restricted high‐voltage tolerance (< 4.5 V vs. Li/Li⁺) and unstable interfacial compatibility.
