(a) TEM image of CNT-PdPt, with corresponding EDX spectrum (inset). (b) Size distribution histogram of nanoparticles in CNT-PdPt. The solid line in the histogram graph represents a Gaussian fitting curve. Inset is the high resolution image of deposited nanoparticles. (c) XRD patterns of thiolated CNT, Pd foil, Pt foil, and CNT-PdPt. (d) Room temperature Raman spectra of thiolated CNT and CNT-PdPt obtained with laser excitation at 514.5 nm, where and denote and band intensities, respectively.
