Mesoporous N,S‐Dual‐Doped Carbon Nanoreactors via Entropy‐Driven Interface Self‐Assembly for Efficient H2O2 Electrosynthesis

Angewandte Chemie, EarlyView.
An entropy‐driven interface self‐assembly strategy is proposed for the controllable synthesis of mesoporous N,S‐dual‐doped carbon nanoreactors. The N,S‐dual‐doping sites optimized the *OOH adsorption, boosting the 2e− selectivity, while the favorable mesostructure accelerated O2 enrichment.

Ordered Pt3Mn Intermetallic Nanoparticles Supported on Atomically Dispersed Mn–N–C as Electrocatalysts for Fuel Cells

Angewandte Chemie, EarlyView.
Ordered L12‐Pt3Mn intermetallic alloys are uniformly deposited onto atomically dispersed Mn–N–C supports. The synergistic effect between MnN4 sites and Pt3Mn elevates interfacial binding strength and dissolution barriers while favorably weakening *OH adsorption. It delivers exceptional catalytic activity and stability in fuel cells, serving as an ideal

Decoding Carbon Dot Purity by Nuclear Magnetic Resonance

Angewandte Chemie, EarlyView.
NMR spectroscopy tracks the removal of molecular and oligomeric impurities in carbon dots, enabling a (semi)quantitative evaluation of their purity through integrated peak analysis. ABSTRACT Carbon dots (CDs) have attracted increasing attention in recent years and have been widely explored in many fields.

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 ...

A Decoupled Cycling Architecture of Asymmetric Zinc‐Air Battery Unlocks Stable Catalyst Strategy and pH‐Dynamic Influence

Angewandte Chemie, EarlyView.
A decoupled cycling architecture along with cost‐effective membrane and efficient catalyst is developed for asymmetric zinc‐air battery. The decoupled design ensures stable operation of catalyst and the pH‐dynamic influence on battery performance is explored, which provides paths for efficient utilization of pH‐decoupling electrolytes.

Quantitative Photo‐Reforming of Biomass to CO Spurred by In Situ Protonation of Carbon Dioxide Radical Anions

Angewandte Chemie, EarlyView.
A “two‐in‐one” photoreduction strategy enabled by electron‐rich yolk Cd species both remote from and adjacent to sulfur vacancies is delivered to be ultraselective for the reduction of O2 and •CO2− in situ formed on the shell Bi2S3 composition (hole) by water oxidation and oxidative C–C cleavage of various biomass organic acids, furnishing CO with > 99%
