由XRD的结果可知，CN-650的聚合程度最高，片层比较厚，所以负载在

It can be seen from the XRD results that CN-650 has the highest degree of polymerization, and the lamellae are relatively thick, so the platinum particles supported on it appear to be relatively large. When changing the thin area of ​​the film, the platinum particles look similar to CN-450 and CN-550, as shown in Fig. At the same time, we updated this picture in MS

According to the XRD results, cn-650 has the highest degree of polymerization and thick lamella, so the platinum particles loaded on it look relatively large. When the replacement layer is thin, the platinum particles look similar to cn-450 and cn-550, as shown in Fig. At the same time, we updated this picture in MS
