摘要：

Ex situ synthesis is the key: Palladium nanoparticles having a narrow size distribution around 3.6 nm have been synthesized in a liquid phase and then loaded onto a carbon support with an overall efficiency of 85%. The resulting nanoparticles, which retained their size and morphology, were exceptionally active and selective as a catalyst for the direct formation of H 2O2 from H2 and O2 in ethanol.
