“…Ni L edge data of NR-Ni(OH) 2 reveals a generally similar profile to that of β-Ni (OH) 2 , which implies that both samples have very similar local chemical environment. This result suggests that all Ni atoms in NR-Ni(OH) 2 are arranged in NiO 6 octahedron, which agrees well with our previous report 15 . However, some mismatch exists between NR-Ni(OH) 2 and β-Ni(OH) 2 as all the peaks are broader for NR-Ni(OH) 2 .…”

“…The low dose scanning transmission electron microscopy (STEM) indicates that more than 89% of NR-Ni(OH) 2 are double-layer in our previous work 15 . Based on the statistical orientation of NR-Ni(OH) 2 , only 1/3 will be oriented with Hǁ c axis on average.…”

“…Properly ordered mesoporous hydroxide thin films with self-assembly of size-tailored nano building blocks was reported by Naoki Tarutani [47]. Arshid Numan [48] synthesized nickel hydroxide of nano-size and X. P. Wang [49] studied strain stabilized nickel hydroxide nano ribbons for effective water splitting.…”

“…Meanwhile, compared with AS‐Ni(OH) 2 and Bulk Ni(OH) 2 , the white line of VR‐Ni(OH) 2 and VP‐Ni(OH) 2 has a noticeable decline, and means that the geometric local structure (such as coordination number, bond length) around Ni atom has changed slightly . Thus, the Ni K‐edge extended XAFS (EXAFS) k 2 χ ( k ) oscillation curve derived from Figure d was presented in Figure e, and displays a significant amplitude difference in 2–8 Å in changed by the local structure distortion of NiO 6− x polyhedron . Furthermore, from the Fourier transform curves (FTs) of k 2 χ ( k ) spectra (Figure f; see Table S1), the Ni‐O peak (2.01 Å) for VR‐Ni(OH) 2 presents a shift in the position towards a lower length.…”
