Dongjiang Yang et al. synthesized g-C 3 N 4 /TiO 2 (B) nanofibers with selective
exposure of high-energy (001) plane and applied it to the degradation of
sulforhodamine B (SRB) dye. Figure 7.9 revealed that the diffraction spots of
electron diffraction pattern (EDP) of samples could be indexed as (110), (1–10),
