Abstract
The g-C3N4 nanosheets were uniformly grown on TiO2 nanotubes with porous structure via the improved methods of impregnation calcination and facial vapor deposition. The photocatalytic performance of the g-C3N4/TiO2 nanotubes was evaluated by the degradation of methyl orange solution (MO) and exhibited higher photodegradation rate than the pure g-C3N4 or TiO2 nanotubes under xenon light irradiation, which may be attributed to the increased specific surface area and efficiently separation of photon-generated electrons/holes by the heterostructure. This work provides a simple and efficient scheme of manufacturing porous heterostructure nanotubes for environmental and energy applications.
