ZnIn2S4 hybrid with MoS2: A non-noble metal photocatalyst with efficient photocatalytic activity for hydrogen evolution

We report the synthesis of ternary zinc indium sulfide hybrid with few-layer MoS2 via a sequential two-step hydrothermal method. The products were characterized by TEM, HR-TEM, XPS, XRD, and DRS. The visible-light induced photocatalytic activities for hydrogen evolution were also evaluated. The result showed that the nanohybrid with a loading amount of MoS2 at 0.5 wt% manifested a superior H-2-production rate under visible light irradiation (lambda > 420 nm). The enhanced photocatalytic activity is mainly attributed to the synergistic effect of enhanced specific surface area, effective electron-hole pair separation and boosted catalytic active sites. This work may contribute to the design and construction of non-noble metal photocatalyst. (C) 2017 Elsevier B.V. All rights reserved.
