The MoS
2
/CdS nano-
heterostructures were synthesized
by using one-pot approach.
The H
2
evolution rate of MoS
2
/CdS
is 162 times higher than that of
pristine CdS.
The extraordinary performance is
attributed to the well-defined
heterostructures.
The photocatalytic mechanism
was detailedly investigated.

abstract
Exploration of cost-efficient and high-performance photocatalyst for H
2
evolution by using
a facile approach is of great importance. In this manuscript, a facile one-pot method was
employed to fabricate MoS
2
/CdS heterostructures with MoS
2
intimately grown on the
surface of CdS resulting in the formation of well-defined heterostructures. Screen experi-
ment reveals the optimized photocatalytic H
2
evolution performance of MoS
2
/CdS is far
exceeding that of pristine CdS by a factor of more than 162. The outstanding performance
can be ascribed to the formation of heterostructures which accelerate charge trans-
portation and separation, and the MoS
2
serving as a cocatalyst for the decrease of H
2
overpotential. Moreover, the photocatalytic mechanism of the MoS
2
/CdS was carefully
