Abstract Combining the peculiar properties of different ingredients in one ultimate material is an efficient route to achieve the desired functional materials. Compared to 2H-MoS 2 , 1T-MoS 2 nanosheets display the perfect performance of hydrogen evolution reaction (HER) because of the excellent electronic conductivity. However, how to further realize HER in the visual and near-infrared (NIR) region is a great challenge. Herein, we develop an efficient method to locally pattern h-MoO 3 on the ultrathin metallic 1T-MoS 2 nanosheets and obtain the novel heterostructures of h-MoO 3 /1T-MoS 2 . The enhanced photoelectrochemical performance of the as-prepared heterostructures has been demonstrated. Our study indicates it is originated from the synergistic effect between h-MoO 3 and 1T-MoS 2 , i.e., the strong optical absorption of h-MoO 3 in the visible and NIR region, the excellent electronic conductivity of 1T-MoS 2 and as well as the efficient separation of the photo-induced carriers from the heterostructures.
