“…low separation efficiency of photogenerated carriers and the low conduction band for H 2 production, to hinder the photocatalytic application of BiVO 4 in water splitting [4]. Therefore, coupling with another semiconductor to build up a new composite has been proved to be an effective way to suppress charge recombination, such as BP/BiVO 4 [5], BiVO 4 /2D g-C 3 N 4 [6], BiVO 4 /Ti 3 C 2 [7], WO 3 /BiVO 4 [8], MoS 2 /BiVO 4 [9] and so on.…”

An efficient photocatalyst has an important role in the photocatalytic water splitting using solar energy to produce hydrogen and oxygen. In this paper, MoSSe/BiVO4(010) heterostructure photocatalyst was constructed to solve the problem of low efficiency of individual photocatalysts. The results of first-principles calculations show that this composite structure has the photocatalytic mechanism of Z- scheme heterostructure, which is helpful for improving the photocatalytic efficiency. Calculations of Gibbs free energy changes confirm the thermodynamic feasibility of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in MoSSe/BiVO4(010) heterostructures. These results indicate that the MoSSe/BiVO4(010) heterostructure has great application potential for visible-light-driven water splitting.
