The density of Br– adsorbed on the Pd {111} facets is high, enhancing adsorption of CTA+ through electrostatic forces and thereby yielding Pd MTNPs of high oxidation resistance. In contrast, the density of adsorbed Cl– is comparatively low, resulting in low adsorption of CTA+ and oxidative etching of the Pd surface.
