CO2‐Responsive Smart Wood Scaffold for Natural Organic Matter Removal without Secondary Pollution

open access: yesAdvanced Materials, EarlyView.
A CO2‐responsive smart wood scaffold is developed for sustainable water purification, achieving efficient natural organic matter (NOM) removal and microbial disinfection without secondary pollution. The CO2‐responsive polymer coating undergoes protonation upon CO2 exposure, enabling strong cation−π interactions with NOM.

Local Charge Density Enhancement Strategy in Nitrogen‐rich Covalent Organic Framework for Boosted Iodine Removal From Water

open access: yesAdvanced Science, EarlyView.
The covalent organic framework, phen‐TPA, is designed for efficient iodine removal from aqueous solutions, featuring optimized iodine‐binding N‐sites. It shows the fastest iodine removal kinetics for I2 and the highest capacity for I3−. Large‐scale flow‐through tests demonstrate its effective separation of I2 and I3− in high‐salinity environments ...

Two‐Step Tandem Catalysis for High‐Efficiency Ammonia Synthesis Via Nitrate Reduction on Anion‐Intercalated CoNi LDH and Cu/Cu2O

open access: yesAdvanced Science, EarlyView.
By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.
