Stand for selectivity! In their Communication on
page 1775 ff., J. P&
eacute;rez-Ramírez et al. show the outstanding selectivity of ligand-modified Pd nanoparticles for direct H
2O
2 synthesis. The hybrid nanostructure makes possible the vertical adsorption of the OOH intermediate on the surface, preventing undesired dissociation and over-hy
drogenation paths. The configuration is stabilized by electrostatic interactions with the ligand, as illustrated by the threads holding the Pinocchio marionette.
