Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

Angewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

DETERMINATION OF THE MASSES OF MINOR PLANETS J.-F. Bange, A. Bec-Borsenberger

The observations of minor planets are of particular interest for determining a possible rotation between the Hipparcos and the dynamical reference frames. In order to evaluate it, Hipparcos data are compared to the values calculated from the equations of

Natural Sunlight IR‐Driven Highly Efficient Synthesis of Acetaldehyde From Bioethanol Over Cu/Fe2O3

Angewandte Chemie, EarlyView.
This work reports a Cu/Fe2O3 catalyst for the conversion of bioethanol into valuable acetaldehyde and green hydrogen under both infrared (IR) light and natural sunlight. This IR‐driven system sets a new performance benchmark, with TON and initial TOF enhanced by at least one order of magnitude, enabled by a constructed IR photon‐to‐phonon channel and ...

Anchored Oxygen‐Release‐Suppression Phase Stabilizing High‐Voltage Ni‐Rich Cathode Materials

Angewandte Chemie, EarlyView.
A one‐step dual‐structure strategy was proposed to synthesize LiNi0.9Co0.05Mn0.05O2 (DA‐NCM) material, which is rich in oxygen vacancies and coated with a perovskite‐type La4LiNiO8 layer stabilized by La─O anchoring provided by La2Mo2O9. This strategy effectively suppressed structural degradation and oxygen release, thereby achieving stable high ...
