Fig. 1 Structure of the laser-chemical tailored spongy Ni(TPA/TEG) catalyst. Structure of the laser-chemical tailored spongy Ni(TPA/TEG) catalyst. (A) Scanning TEM (STEM) images and energy-dispersive x-ray spectroscopy (EDX) mapping of the spongy Ni(TPA/TEG) nanostructure. (B) STEM image of the Ni(TPA/TEG) particles. (C) Three-dimensional tomographic reconstruction of a fraction of spongy Ni(TPA/TEG) composite (movie S1). (D) TEM image of the spongy Ni(TPA/TEG) nanostructure. The inset high-resolution TEM image displays the defective (020) lattices [d(020) = 1.02 nm] of an orthorhombic crystal. (E) Scanning electron nanodiffraction series taken from the Ni(TPA/TEG) particle by a scanning nanoprobe with an electron beam size of ~3 nm. The probe step size is 10 nm with an exposure time of 0.5 s at each step and a total beam current of ~5 pA. (F) Diffraction patterns showing the [100] and [111] orientations of the orthorhombic Ni(TPA/TEG) composite (movies S2 and S3). The dimensions of the diffraction patterns are 11.9 nm−1 × 11.9 nm−1.
