Fig 32 TEM(a), HR-TEM(b), and SAED(c)images of CoP NP; SEM(d), TEM(e), HR-TEM(f), SAED(g), STEM(h), and elemental mapping(ⅰ)of CoP NR110 The inset in the framed area of(b)is FFT(fast Fourier transform)obtained from the yellow framed area of(b).The inset in the yellow framed area of(f)is FFT corresponding to the characteristic(011)facet of CoP, and the inset in the red framed area of(f)corresponds to the characteristic(111)facet of CoOx.The spots observed on the FFT are indicative of the registry order and the crystallinity. The lattice fringe spacings of the materials were determined using FFT.
