摘要：

Constructing heterojunction is one of the methods to restrain the hole-electron recombination and thus improve the photoelectric property. In this work, PbS nanoparticles were grown directly on ultra thin MoS2 nanosheets to fabricate 2D MoS2/PbS nanocomposites via a facile one-pot solvothermal route. PbS nanoparticles anchored on MoS2 sheets exhibited high crystallinity and uniformity. The particle size can be controlled by varying the precursor concentration. The nanocomposites displayed higher photocurrent compared with pristine MoS2, due to the improved light harvesting and the construction of p-n heterojunction structure.
