Co-catalyst MoS2-nanosheets/TiO2 nanotubes for the enhancement of photocatalytic hydrogen production

Abstract

The MoS2 nanosheets/TiO2 nanotubes heterojunctions are designed for enhancing photocatalytic hydrogen production. The results of XRD, SEM and TEM imply that the heterojunctions are successfully prepared via electrostatic spinning technology and hydrothermal co-deposition method. Besides, the results of UV and PL display that the MoS2 nanosheets enhance the absorption of visible light, drive the transfer of photo-electro and promote the separation of photo-generated carries. Further, compared with the pure TiO2 nanotubes, the heterojunctions exhibit excellent photocatalytic hydrogen production enhancement of about ∼340.739μmol/g.h, which is about 7 times of pure TiO2 nanotubes.
