TiO2/g-C3N4 nanofibers were prepared by electrospinning method.
TiO2/g-C3N4 nanofibers with diameter of 100–200 nm.
The composite nanofibers displayed the best photocatalytic degradation on RhB, when the g-C3N4 content was 0.8 wt.%.
The heterojunction formed between TiO2 and g-C3N4 contributed to the improved separation of electron-hole pairs.
