“…Figure 1A shows the diffraction peaks of MCS and CPO and their standard diffraction peaks. It can be clearly seen that MCS has seven distinct characteristic peaks at 2θ = 25.04°, 26.79°, 28.47°, 36.89°, 44.12°, 48.36°, and 52.35°, corresponding to the rod‐shaped MCS (100), (002), (101), (102), (110), (103), and (112) crystal planes (JCPDS # 89‐443) 27 . And several distinct characteristic peaks of CPO appear at 11.32°, 13.32°, 18.31°, and 30.41°, corresponding to (110), (020), (200), (201) crystal planes of CPO (JCPDS # 41‐0375) 26 .…”
