MoS2/TiO2 Edge-On Heterostructure for Efficient Photocatalytic Hydrogen Evolution

Abstract

Via edge engineering, a facile two-step method is demonstrated that produces solid edge-on junctions between TiO2 and few-layered MoS2 in large scale. MoS2/TiO2 edge-on heterostructures result in high conductive MoS2/TiO2 interfaces and optimized electron transport pathways that facilitate the electron–hole pair separation, leading to an efficient solar water splitting.
