Hydrogen production activity of MoS2-ZnIn2S4 nanocomposite under visible light irradiation

Mool Chand et al.

Summary: In this manuscript, the synthesis of MoS2-ZnIn2S4 nanocomposite using hydrothermal and chemical aqueous methods under low temperature was reported. The photocatalytic activities of the MoS2-ZnIn2S4 nanocomposite for H-2 production under visible light were investigated. The results showed that the addition of MoS2 as a co-catalyst increased the H-2 production rate of ZnIn2S4, and the MoS2-ZnIn2S4 nanocomposite exhibited a higher rate of hydrogen production compared to pure ZnIn2S4. The increased rate of H-2 production activity was attributed to the synergistic combination of increased specific surface area, efficient electron-hole pair separation, and amplified catalytic active sites. This work has the potential to contribute to the development of low-cost and low-temperature or template-free synthesized semiconductors for hydrogen production.
