Compréhension moléculaire de la chimie de surface: un outil pour la préparation de catalyseurs à site unique et bien au delà…
The rational design and development of catalysts require structure – reactivity relationship approach, hence the need for strategies to obtain well-defined surface sites and their detailed characterization. Here, we first discuss the method to control and understand the chemistry at the surface of materials towards the development of well-defined – so-called single-site – heterogeneous catalysts and show how this approach can bring about information about industrial catalysts. In this context, we will show how Dynamic Nuclear Polarization Surface Enhanced NMR spectroscopy can provide insightful information about material active site structures, which are not available by other characterization techniques.
