Synthesis of CoAl-LDH nanosheets and N-doped graphene nanocomposite via Successive Ionic Layer Deposition method and study of their electrocatalytic properties for hydrogen evolution in alkaline media

Copper Aluminum Layered Double Hydroxides with Different Compositions and Morphologies as Electrocatalysts for the Carbon Dioxide Reduction Reaction

“…The Fourier-transform infrared (FTIR) spectra of synthesized LDHs are shown in Figure S1. Absorptions originating from anion species, water molecules, and metalÀ O bonds were observed, [34][35][36] which are essentially similar to previously reported LDHs.…”

Atomic scale modulation strategies and crystal phase transition of flower-like CoAl layered double hydroxides for supercapacitors

“…3d includes three peaks located at 530.8, 531.7 and 532.4 eV, which are consistent with Co–O, O–O and adsorbed oxygen, respectively. 35 Comparing the Al 2p spectra of CoAl LDH and CoOOH, a peak at 74.6 eV in Fig. 3e disappears after removal of the Al element, which also can demonstrate the successful synthesis of CoOOH.…”

Understanding the oxygen evolution activity trend in Co2Fe LDH‐N doped graphene hybrids

“…The peaks at about 285, 400, and 535 eV corresponds to C‐1s, N‐1s, and O‐1s, respectively. [ 33–35 ] The N‐1s high resolution XPS spectrum in Figure 8b shows two peaks at 400.2 and 404.4 eV. The later is due to the nitrate ions present in the interlayer spacing of LDH.…”

“…The peaks due to pyrrolic (399.5) and graphitic N (400.5), present in NG are observed on deconvolution of the peak at 400.2 eV. [34,35] The deconvoluted high resolution XPS spectrum for O-1s in Figure 8c shows different chemical environments for oxygen in the hybrid. The peaks at 531.3 and F I G U R E 7 TEM images of 75LDH at (a) low resolution (Inset shows the SAED pattern), and (b) high resolution.…”
