The 2D petaloid MoS2 lamellas modified cubic CaTiO3 nanocomposites towards photocatalytic hydrogen production enhancement

The 2D petaloid MoS2 lamellas modified CaTiO3 nanocomposites are fabricated via a simple two-step hydrothermal method. There, the as-prepared MoS2/CaTiO3 nanocomposites exhibit a remarkable photocatalytic HER enhancement of about ∼30 folds than the unmodified CaTiO3 and a decent photocatalytic stability, which can be mainly ascribed to the modification of the MoS2 lamellas, there, the MoS2 with lower Fermi level can capture the photoelectron for improving the charge carriers transferring, and the ultrathin lamellas nanostructure can provide sufficient HER active sites and shorten reaction time to improve the photocatalytic HER performance and stability.
