Abstract

To overcome rapid electron-hole recombination and the need for employing noble metals as co-catalysts for photocatalytic water splitting, the present work reports on the fabrication of bismuth sulphide (Bi ₂ S ₃ )-modified molybdenum disulphide (MoS ₂ ) as an efficient hybrid photocatalyst. Under simulated solar light irradiation, the Bi ₂ S ₃ /MoS ₂ photocatalyst with an optimum molar ratio of Mo to Bi of 50% (mol/mol) achieved a H ₂ production rate of 61.4 μmol/h. The photocatalytic enhancement was attributed to an effective charge transfer mechanism between Bi ₂ S ₃ and MoS ₂ , as evidenced by photoelectrochemical characterization. A plausible reaction mechanism over the as-prepared Bi ₂ S ₃ /MoS ₂ photocatalyst was also proposed based on the experimental results obtained.
