Plasmon-Enhanced Photoelectrochemical Current and Hydrogen Production of (MoS2-TiO2)/Au Hybrids

Abstract Three component hybrid (MoS2-TiO2)/Au substrate is fabricated by loading plasmonic Au nanorods on the MoS2 nanosheets coated TiO2 nanorod arrays. It is used for photoelectrochemical (PEC) cell and photocatalyst for hydrogen generation. Owing to the charge transfer between the MoS2-TiO2 hete...
