Reconstructed Bi‐Sn Interfacial Sites Coupled with a Supramolecular Cation Cage Enable Low K+ Acidic CO2 Electroreduction to Formate

Advanced Energy Materials, EarlyView.
Pyrochlore‐derived Bi–Sn interfaces enable selective CO2 electroreduction to HCOOH in strongly acidic media (pH = 1). Interfacial electronic coupling promotes *OCHO formation while suppressing hydrogen evolution. Cryptand‐driven cation regulation enriches interfacial K+, maintaining high HCOOH faradaic efficiency of 94% even at low K+ electrolyte ...

A New Switchable Zr12 Oxocluster Based Large Pore Metal–Organic Framework Functionalized With Spin Crossover Complexes for Acetic Acid Colorimetric Sensing

Angewandte Chemie, EarlyView.
We present here (1)⊂MIP‐216(Zr), a new hybrid material composed of an FeII spin crossover complex (1) loaded in the pores of a new hydrophobic metal–organic framework (MIP‐216(Zr), that presents a high affinity toward acetic acid and acts as a highly sensitive colorimetric sensor of acetic acid vapor due to a spin state switching of the encapsulated ...

CO2‐to‐CO Electrochemical Conversion With an Fe(I) Porphyrin Complex in Water

Angewandte Chemie, EarlyView.
Using in situ UV–vis/IR spectroelectrochemistry, we track CO2 reduction by a water‐soluble iron porphyrin. Rather than the usual [Fe0] intermediate in organic solvents, CO2 binds the electrogenerated [FeI] species and undergoes reductive C─O cleavage to stable [FeII‐CO]. This previously unexplored reaction pathway is facilitated by an aqueous H‐bonding

Metabolische Untersuchungen lebender Zellen im Minutentakt, ermöglicht durch schnelle Parawasserstoff‐basierte Hyperpolarisation

Angewandte Chemie, EarlyView.
Die schnelle Parawasserstoff‐Hyperpolarisation in Kombination mit einfacher Verdünnung ermöglicht die Zufuhr von hyperpolarisiertem, biokompatiblen Pyruvats zu immobilisierten lebenden Zellen innerhalb von ≈1 min. Wiederholte Substratinjektionen offenbaren frequenzabhängige metabolische Dynamiken und eröffnen damit eine neue zeitliche Dimension für ...

Reaction Environment Engineering for Selective C3+ Formation in CO2 Electroreduction: Progress and Perspectives

Angewandte Chemie, EarlyView.
This work focuses on how to improve the selectivity and activity of electrocatalytic CO2 reduction to C3+ products, by the integration of electrocatalyst and electrolyte co‐design. We summarize key C3+ formation mechanisms and provide a comprehensive reaction network through thermodynamic analysis.

The Role of Zn–Hf Site Proximity and Oxygen Vacancies for Methanol Formation Over ZnHfOx Catalysts Under CO2 Hydrogenation Conditions

Angewandte Chemie, EarlyView.
ZnHfOx catalysts enable highly selective hydrogenation of CO2 to methanol over a wide range of Zn contents, as the Zn‐VO‐Hf active motif (VO = oxygen vacancy) exists not only in solid solution‐type ZnHfOx for low Zn contents (≤ 35 mol%), but also as HfOx cluster/single atom decorated ZnO surfaces for Zn contents > 95 mol%.

Electrochemically Induced Structural Evolution to Generate Optimized High‐Entropy‐Alloy Electrocatalysts for Ethanol Oxidation

Angewandte Chemie, EarlyView.
Electrochemical cycling drives spontaneous facet optimization in high‐entropy Pd@PdPtIrRuRh core‐shell nanocrystals, reshaping simple cubes into severely beveled architectures with balanced {100}/{110}/{111} facets. This dynamic restructuring yields active electrocatalysts that favor complete ethanol oxidation via the C1 pathway, suppress strongly ...

Dual Activation of H2 and CO2 by a Pincer‐Type Ni–Zn Heterobimetallic Complex

Angewandte Chemie, EarlyView.
A bimetallic Ni−Zn complex performs sequential activations of H2 (1 equiv) and CO2 (2 equiv). This bimetallic cooperativity is attributed to the weak Lewis acidic nature of Zn(II), which promotes fluxional ligand binding. Namely, an X‐type ligand at Ni, where X is hydride or formate, toggles between two different binding modes: bridging Zn(μ‐X)Ni and ...
