Maximizing Active Site Density in Tin Single‐Site Catalysts for Selective Carbon Dioxide to Formate Electroreduction

Angewandte Chemie, EarlyView.
High‐loading tin single‐site catalysts (>7.5 wt.% Sn) are synthesized using a nitrogen‐enriched carbon scaffold and mechanochemically assisted pyrolysis to stabilize atomically dispersed Sn. The resulting Sn/N‐C‐M catalyst enables highly selective CO2‐to‐formate conversion (>90% FE across 50–500 mA cm−2) with long‐term durability and operando‐verified ...

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

Angewandte Chemie, EarlyView.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Axial Boron Coordination Reconstructs Stereostructure of Cu Single‐Atom Nanozymes for Efficient Water‐Phase Chemical Sensing

Angewandte Chemie, EarlyView.
Sun et al. proposed an axial boron coordination strategy to reconstruct the stereostructure of Cu SAzymes and enable them to serve as efficient laccase mimics for high‐throughput smart sensor array detection of phenolic pollutants in water phases. ABSTRACT Developing single‐atom nanozymes with stereoconfigurations is a new paradigm for biomimetic ...
