7879 662 g-C3N4 nm SEM The SEM images in Fig. 4 show the morphological and structural differences between PCN and CCN. PCN exhibited a fluffy-like structure with a small and irregular dense-texture as compared to CCN texture. These fluffy nanosheets were connected in such a way that they have left a small hollow space between them. In comparison, CCN exhibited a uniform surface texture, and g-C3N4 crystalline sheets were looked like large-sized aggregates. 89.9,11.8 A summary of the comparison of the specific surface area (SBET), total pore volume, and pore width of PCN and CCN are listed in Table 2. PCN exhibited greater SBET (89.9 m2/g) than that of CCN (11.8 m2/g). This enlarged surface area can be attributed to porous, thin, and curled nanosheets in fluffy PCN as compared to crystallized, planar, and large layered nanosheets of CCN.
7895 678 g-C3N4 200 nm TEM TEM (Fig. S2A) and DLS (Fig. S2E) indicate that g-C3N4 nanosheets are nanoflakes with an average size of 200 nm.
