摘      要：Two-dimensional (2D) ultrathin MoS2-modified black Ti^3+-TiO2 nanotubes were fabricated using an electrospinning-hydrothermal treatment-reduction *** TiO2 nanotubes were fabricated via ***,2D MoS2 lamellae were grown on the surface of the nanotubes and Ti^3+/Ov ions were introduced by *** photocatalytic performance of the 2D MoS2/Ti^3+-TiO2 nanotubes was^15 times better than that of *** HER enhancement of the MoS2/Ti^3+-TiO2 nanotubes can be attributed to the Pt-like behavior of 2D MoS2 and the presence of Ti^3+-ions,which facilitated the quick diffusion of the photogenerated electrons to water,reducing the H2 activation *** presence of Ov ions in the nanotubes and their hollow structure increased their solar utilization.
