Determination of Core-Shell Structures in Pd-Hg Nanoparticles by STEM-EDX
The structural and elemental configuration of a high-performing Pd-Hg electrocatalyst for oxygen reduction to hydrogen peroxide has been studied by means of high-resolution scanning transmission electron microscopy. Pd-Hg nanoparticles are shown to have a crystalline core-shell structure, with a Pd core and a Pd-Hg ordered alloy shell.
The ordered shell is responsible for the high oxygen reduction selectivity to H2O2.
