HR-MAS: a key technique to study Nanoparticles

“Phosphine Stabilized Ruthenium Nanoparticles: the Effect of the Nature of the Ligand in Catalysis” David González-Gálvez, Pau Nolis, Karine Philippot, Bruno Chaudret and Piet W. N. M. van Leeuwen. ACS Catalysis, Volume 2, Pages 317-321, January 2012 DOI: 10.1021/cs200633k

Various ligands not forming monometallic complexes were used for Ru nanoparticle stabilization, enabling the control of size, shape and electronic properties. HRMAS NMR spectroscopy allowed us to study surface-bound molecules, evidencing ligand hydrogenation and decomposition of THF during the RuNP synthesis.
