“…The understanding of the formation mechanism and preparation of single crystal or highly crystalline uniform Ni nanoparticles is crucial in many areas of science and technology. 22 Such particles are the materials of choice in the manufacturing of many electronic components including multilayer ceramic capacitors (MLCC), [23][24][25][26] because the oxidation of highly crystalline Ni particles is significantly slower than that of polycrystalline particles due to the absence of internal grain boundaries which favor faster diffusion of oxygen into the crystal. Furthermore, in proton exchange membrane (PEM) fuel cells regular facets of Ni nanocrystals represent an ideal no-strain substrate for carbon 30 or silica coating, 31 as well as epitaxial deposition of continuous thin platinum shells in the preparation of core-shell catalysts with high catalytic efficiency.…”

We report a new approach to achieve growth of highly crystalline nickel nanoparticles over an extended range of sizes (up to 100 nm in diameter) and time scales (up to several hours) by diffusional transport of constituent atoms. The experimental procedure presented offers control of the morphology of the resulting particles and yields base metal nanocrystals suitable for epitaxial deposition of noble metal shells and the preparation of materials with improved catalytic properties. The reported precipitation system also provides a good model for testing a diffusion-driven growth mechanism developed specifically for the reduction process described.
