Entropy‐Stabilized Aluminate Catalysts That Break the Activity–Stability Tradeoff in CF4 Hydrolysis

Angewandte Chemie, EarlyView.
Entropy‐stabilized aluminate breaks the activity–stability tradeoff in CF4 hydrolysis by combining a multication aluminate framework with an entropy‐stabilized lattice. An electron‐deficient Al–O environment is F‐philic but O‐phobic, enabling C–F activation while suppressing H2O poisoning. Under steam‐rich, strongly fluorinating conditions, the entropy‐

Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

Angewandte Chemie, EarlyView.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

Matching the Coupling of Valence Electrons in the Oxide Interface to Perturb the Magnetic Order Enhancing Oxygen Reduction in Zinc–Air Batteries

Angewandte Chemie, EarlyView.
Sub‐5 nm Fe2O3/Sm2O3 heterojunction nanoparticles are anchored on nitrogen‐doped carbon nanofibers, featuring coupled Fe(3d)‐O(2p)‐Sm(4f) orbitals at the interface. The resulting super‐exchange induces antiparallel magnetic ordering at heterointerfaces, suppressing spin‐dependent interaction between surface OH* species and Fe sites to facilitate OH ...
