Heterogeneous catalysis is one of the most important fields of application for shape-controlled nanoparticles. However, before using the nanoparticles, the organic components used during the synthesis must be removed, preferably without changing the size and the superficial structure of the nanoparticles. A facile and novel chemical method is introduced by P. Rodriguez et al. on p. 709 for cleaning Pt nanoparticles with preferential orientation, prepared by colloidal synthesis and coated with polyvinyl pyrrolidone (PVP). The method is based on the idea that the decomposition of hydrogen peroxide may aid in removing organic components from the Pt nanoparticle surface, and does not introduce any major loss of superficial structure.
