Abstract

We utilize direct 17O DNP for the characterization of non-protonated oxygens in heterogeneous catalysts. The optimal sample preparation and population transfer approach for 17O direct DNP experiments performed on silica surfaces are determined and applied to the characterization of Zr- and Y-based mesoporous silica-supported single-site catalysts.
