Bioinspired Atomic Manganese Site Accelerates Oxo …

Herein, taking inspirations from metalloenzymes, we constructed atomically dispersed manganese sites anchored onto conjugated tri-s-triazine units of graphitic carbon nitride as a bioinspired photocatalyst (Mn 1 /tri-CN) for the oxo-dehydrogenation of N-heterocycles.The primary coordination sphere of atomic Mn-N 2 sites (role i: oxygen …

REACTIONS WITH MANGANESE (III) ACETATE

manganese (II) acetate. and other acetates like sodium or potassium. 1.8 The effect of addition of manganese (II) acetate differs from that found of other metal acetates. This change in spectra of manganese (II) acetate is tentatively ascribed to formation of a Mn(III}-Mn(II) interaction complex of mixed valence.

Tri-Manganese(III) Salen-Based Cryptands: A Metal …

Here, we report a series of salen-based tri-manganese (Mn(III)) metallocryptands (1-3) that function as catalase biomimetics. These cage-like molecules contain a unique "active site" with three Mn centers in close proximity, an arrangement designed to facilitate metal cooperativity for the effective dismutation of H 2 O 2 with minimal HO ...

Oxydation et réduction du manganèse

Voilà j'ai besoin d'aide sur le cycle du manganèse en milieu aquatique... Je sais que l'oxydation du manganèse est: Mn(II) + H 2 O 2--> Mn(III) + OH-+ OH --> Mn(IV)O 2 + H 2 Cela ce passe en milieu aérobie. Par contre je ne suis pas sûre pour la réduction en anaérobiose: Mn(IV)O 2 + matières organiques ou inorganiques réduits --> Mn(II ...
