In-depth composition and structural analyses of the Pd59Cu30Co11 nanoalloys. The X-ray photoelectron spectroscopy (XPS) spectra of the as-synthesized dendritic Pd59Cu30Co11 nanoalloys a Pd 3d region, b Cu 2p region, c Co 2p region (the red dash lines in pictures indicate the standard positions of Pd 3d, Cu 2p and Co 2p), d the X-ray absorption near edge structure (XANES) spectra for the Pd K-edge
