Figure 12. (A) The fabrication process of CBC materials: (1) A large-sized BC pellicle (200 × 230 × 3 mm³) was cut into the desired shape with a sharp blade. (2) After freeze-drying of the wet BC pellicles, the ultralight BC aerogel was obtained. (3) Further pyrolysis treatment of the BC aerogel under flowing argon produced the black p-BC aerogel. SEM images of hybrid nanofibers: BC (B); CBC (C); CBC@MnO₂; (D) hybrid nanofibers; and CBC/MoSe₂ (E, F). The inset image in (D) is the photograph of the CBC@MnO₂.
