“…In addition, the XRD pattern of the MnP x @MoP y /N,P-Gr hybrid also confirms the formation of crystalline MnP x and MoP y on the Gr substrate, in agreement with the TEM and EDS results. In detail, a list of peaks at 2θ of 23.7, 32.6, 34.2, 48.4, 53.1, and 57.3° is consistent with the d (110), d (101), d (111), d (121), d (301), and d (320) crystal planes of the MnP x phase, respectively. , Meanwhile, different peaks placed at 2θ of 32.6, 42.5, 57.1, and 64.6° are associated with the d (100), d (101), d (110), and d (111) crystal planes in the MoP y structure, respectively . The effect of reduction and heteroatom doping process toward the structure of Gr is also proven through the Raman analysis, shown in Figure b.…”
