Activation électrochimique du dioxygène par des porphyrines de fer et de manganèse. Vers des oxydations aérobies électrocatalytiques de substrats organiques
Autor: Kostopoulos, Nikolaos
The activation of dioxygen is at the center of current economic challenges, because oxygenation and halogenation reactions play a major role in the chemical industry. These current oxidation processes often use harmful chemical oxidants, or dioxygen

Les polyoxométallates en tant que relais électroniques pour la photosynthèse artificielle
Autor: Ben M'Barek, Youssef
Publikováno v: Material chemistry. Sorbonne Université, 2020. English. ⟨NNT : 2020SORUS189⟩
The photosynthetic process can be roughly summarized in three main steps: light harvesting, charge transport/accumulation and finally catalysis. While photosynthesis is a highly convoluted procedure that would be nearly impossible to reproduce, the d
