Insights into the Catalytic Activity of Nitridated Fibrous Silica (KCC-1) Nanocatalysts from15N and29Si NMR Spectroscopy Enhanced by Dynamic Nuclear Polarization

From The DNP-NMR Blog:

Insights into the Catalytic Activity of Nitridated Fibrous Silica (KCC-1) Nanocatalysts from15N and29Si NMR Spectroscopy Enhanced by Dynamic Nuclear Polarization

Lilly Thankamony, A.S., et al., Insights into the Catalytic Activity of Nitridated Fibrous Silica (KCC-1) Nanocatalysts from15N and29Si NMR Spectroscopy Enhanced by Dynamic Nuclear Polarization. Angewandte Chemie, 2015. 127(7): p. 2218-2221.

Fibrous nanosilica (KCC-1) oxynitrides are promising solid-base catalysts. Paradoxically, when their nitrogen content increases, their catalytic activity decreases. This counterintuitive observation is explained here for the first time using 15N-solid-state NMR spectroscopy enhanced by dynamic nuclear polarization.
