AbstractHerein, molybdenum disulfide (MoS2) integrated on Si pyramids was used as a co-catalyst to improve charge separation efficiency. Various quantities of phosphorus (P) heteroatoms were doped into MoS2 materials to boost catalytic performance. Raman and extended X-ray absorption fine structure spectra showed that the introduction of P dopants increased the number of exposed edges and sulfur vacancies that acted as hydrogen evolution reaction (HER) active sites on MoS2 and enhanced photoelectrochemical activity. Density functional theory calculations revealed that the HER inert basal plane of MoS2 became catalytically active after P atoms doping. MoS1.75P0.25/Si pyramids presented the optimal onset potential of +0.29 V (vs. RHE) and current density -23.8 mA cm(-2). A titanium dioxide (TiO2) layer was prepared through atomic layer deposition and served as a passivation layer that improved photocathode stability. The photocurrent retention of MoS1.75P0.25/10 nm TiO2/Si pyramids was 84.0% after 2 h of chronoamperometric measurement.
