Abstract
Constructing mixed heterostructures are often designed as a photoelectrocatalytically active interface to facilitate the separation of photo-induced charge carriers, thus improving photoelectrochemistry device performance. Herein, two dimensional Ti3C2/MoS2 heterostructures were successfully synthesized by liquid phase exfoliation and electrophoretic deposited methods. The photocurrent density was further improved to approximate 3.4 μA cm−2 at the ratio of MoS2/Ti3C2 (1:1). This enhanced photoelectric response in mixed heterostructure is caused by strong photon absorption, efficient charge separation and high carrier density. This work provides a way to enhance the photoelectrochemistry water splitting performance by tuning the nanosheet size and controlling the rational hierarchical.
