Coordination confinement pyrolysis to Flower-like nanocomposites composed of ultrathin nanosheets with embedded ultrasmall CoP nanoparticles for overall water splitting

Structural regulation of Co-based coordination polymers by adjusting solvent polarity toward electrocatalytic hydrogen evolution performance

“…The I D / I G value of 2D-500 is 1.04, which is larger than that of 3D-500 ( I D / I G = 0.98), which indicates that the content of disordered carbon is more in 2D-500 . 43–45 The XRD patterns of the two catalysts after pyrolysis were also obtained (Fig. 5d).…”

Rational Construction of 3D Self‐Supported MOF‐Derived Cobalt Phosphide‐Based Hollow Nanowall Arrays for Efficient Overall Water Splitting At large Current Density

“…[47,48] The XRD pattern displays the weak diffraction peaks for CoP-based composite samples, which may be attributable to the weak crystallinity resulted from the small grain size of CoP phase. [49] As shown in Figure 3a, no clear Co diffraction peak at 44.2°is observed, demonstrating that most of the metallic Co NPs are converted to CoP NPs during low-temperature phosphatization process. The structure and morphology of all Co-based samples are characterized using Raman spectrum (Figure 3b), where the peaks at 1358 and 1590 cm −1 correspond to the D and G bands of carbon, respectively.…”
