Hierarchical Hollow Nanoprisms Based on Ultrathin Ni‐Fe Layered Double Hydroxide Nanosheets with Enhanced Electrocatalytic Activity towards Oxygen Evolution

Ni‐Fe‐Doppelschichthydroxide (LDH) sind vielversprechende Elektrokatalysatoren der Sauerstoffentwicklung (OER) in alkalischen Elektrolyten. In ihrer Zuschrift (DOI: 10.1002/ange.201710877) beschreiben X. W. Lou et al. die Synthese hierarchischer hohler Nanoprismen aus Ni‐Fe‐LDH‐Nanoschichten durch Selbsttemplatisierung. Diese Nanoprismen zeichnen sich durch große Oberflächen und hohe elektrokatalytische Aktivität in der OER aus, bei niedriger Überspannung, einer geringen Tafel‐Steigung und guter Stabilität.

    Productive Cascade

    Starting from available chemicals, a German team of researchers successfully completed the total synthesis of agarozizanol B, an interesting natural substance found in agarwood. As described in the journal Angewandte Chemie, the key sequence in the relatively short synthetic pathway is a ph ... more

    Hard Single-Molecule Magnets

    Magnets formed from a single molecule are of particular interest in data storage, since the ability to store a bit on every molecule could vastly increase the storage capacity of computers. Researchers have now developed a new molecular system with a particular magnetic hardness. The ingred ... more
