Abstract:
Formic acid adsorption on ruthenium nanoparticles of different sizes allows differentiation of differently bound formate species by solution (13)C NMR spectroscopy (see picture). The chemical shifts are comparable to those of organometallic analogues, thus indicating that formate can act as a probe to distinguish surface features of metallic nanoparticles in solution with good quantification and resolution.
