Hydrogen production through photoelectrochemical (PEC) water-splitting process has drawn significant research attention because it is promising clean source of energy for improving earth climate in the future. Molybdenum disulfide (MoS2) belongs to the class of transition metal dichalcogenides (TMDCs) that are being extensively utilised as favourable electrocatalysts in PEC electrodes and powerful cocatalysts in photocatalysts for HER. It is also received significant consideration because of low-cost and earth-abundant catalysts that can replace noble metals, such as Pt. In this study, two methods were used for the fabrication of MoS2 using chemical vapor deposition (CVD) which were sulfurization of MoO3 and chemical solution method. Raman spectrums confirm the presence of the MoS2 layers on SiO2/Si. MoS2 fabricated using sulfurization of MoO3 produced higher photocurrent density for photoelectrochemical (PEC) water splitting as compared to the chemical solution method which were -0.07 mA cm−2 at -0.2 V versus RHE and -0.05 mA cm-2 at -0.2 V versus RHE, respectively. This study demonstrated that MoS2 is promising photocathode for PEC solar fuel application.
