A High‐Capacity Semiconductor Organic Polymer for Stable Aqueous Ammonium‐Ion Storage

open access: yesAdvanced Materials, EarlyView.
The dual challenges of solubility and low conductivity in aqueous ammonium ions storage using the tetraamino‐p‐benzoquinone material are addressed through an amidation reaction and the conjugation effect. The delocalization of electrons facilitates rapid charge transport and collection.

Ultrathin Mesoporous Metal‐Organic Framework Nanosheets

open access: yesAdvanced Materials, EarlyView.
A bottom‐up interface‐directed co‐assembly strategy enables the synthesis of ultrathin 2D mesoporous UiO‐66(Ce) nanosheets with tunable thickness and uniform mesopores. The enhanced mass transport and accessible active sites significantly improve performance, highlighting the synergistic effects of 2D morphology and mesopores in metal‐organic ...

Modulating Single‐Atom Pt Coordination for Enhanced Low‐Temperature Ammonia Fuel Cell Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
A bifunctional Pt single‐atom catalyst (Pt‐DG‐1) is discovered with enhanced ammonia oxidation reaction and oxygen reduction reaction mass activities compared to commercial Pt/C. It is shown that modulating the coordination environment of Pt single atoms is crucial towards dictating the electrocatalytic activity.
