Abstract

In this paper, molybdenum disulfide (MoS_2) was hybridized with graphene carbon nitrite (g-C_3 N_4) and Cu2O in consideration to heighten the photoelectrochemical (PEC) action and increase the light absorption range of Cu2O thin film. The melamine powder was poured in an empty container and then heated in a furnace to attain theg-C_3 N_4 powder. The ternary hetero-epitaxial growth was achieved by growing of MoS_2/g-C_3 N_4 on the 〖Cu〗_2 O hybrid by a partial thermal oxidation process. The characteristics of MoS_2/g-C_3 N_4/〖Cu〗_2 O hybrid film were investigated through XRD, FT-IR and photoelectronchemistry-related measurements. The PEC performance of the treble amalgam electrode was investigated by means of current-voltage test under illumination. The efficiency calculated from current-voltage test under illumination exhibited that the incidence of graphene carbon nitrite and molybdenum disulphide inside the coating networks, regardless of its low down content, may perhaps stimulate substantial improvement in maximum photoconversion effectiveness from 0.036% to 0.33%. This bettering is deducible to the enrichment of the electron-reassign proficiency au courant the incorporation of g-C_3 N_4 and MoS_2, as corroborate by X-Ray Diffraction Analysis (XRD). The PEC investigation results signify that the photoelectrochemical action of the MoS_2/g-C_3 N_4/〖Cu〗_2 O ternary hybrid is much higher than that of 〖Cu〗_2 O subtrate. The mechanisms accountable for the enhanced PEC behavior of the MoS_2/g-C_3 N_4/〖Cu〗_2 O triplex hybrid are deliberated in detail.
