Facile ultrasound-driven formation and deposition of few-layered MoS2 nanosheets on CdS for highly enhanced photocatalytic hydrogen evolution

MoS2 nanosheet incorporated α-Fe2O3/ZnO nanocomposite with enhanced photocatalytic dye degradation and hydrogen production ability

“…In addition to these, the unique structure of MoS 2 nanosheets may play a key role by yielding plenty of exposed edges with coordinately unsaturated S atoms as activity sites which can accept the accumulated photoinduced electrons on MoS 2 for reducing H + to H 2 gas and thus, leads to the discerned high photocatalytic H 2 production potential. 49 …”

“…46 The enhancement in photocatalytic H 2 generation due to incorporation of ultrasonicated MoS 2 in a-Fe 2 O 3 / ZnO nanocomposite can be associated with the exposed active edge sites and the accelerated charge transfer rate at the interface by few-layer MoS 2 nanosheets. 49 The outcome of this hydrogen production test suggests that the solar energy conversion efficiency of a-Fe 2 O 3 /ZnO nanocomposite was improved by incorporating few-layer MoS 2 nanosheets and can be further increased by integrating it with monolayer MoS 2 nanosheets. This is due to the fact that monolayer MoS 2 shows a number of unique photo-electro properties 40,50 which may be favorable for accelerating H 2 evolution reaction albeit the synthesis of monolayer MoS 2 is quite complex and cumbersome.…”

Prominent roles of Ni(OH)2 deposited on ZnIn2S4 microspheres in efficient charge separation and photocatalytic H2 evolution

“…[14][15][16] Both experimental and computational results also well revealed the photogenerated charge transfer, capture, and active sites for H 2 production in the systems with MoS 2 as a cocatalyst. 17,18 Aerward, other transition metal (e.g. Ni, Co, Cu, Fe) disuldes and phosphides have been investigated and utilized as cocatalysts for assisting photocatalytic H 2 production.…”
