Abstract

original image

As nutty as a fruitcake! PdSx seed-mediated growth has led to the formation of heterostructured Pd–Co–Pd sulfide peanut-shaped nanoparticles, which were generated by fusing two Co–Pd sulfide acorn-shaped nanoparticles with the Co9S8 phases aligned in the same crystallographic orientation (see TEM image).
