title: Temperature-Mediated Selective Growth of MoS2/WS2and WS2/MoS2Vertical Stacks on Au Foils for Direct Photocatalytic Applications.
abstract: A growth-temperature-mediated two-step chemical vapor deposition strategy is designed to synthesize MoS2/WS2and WS2/MoS2stacks on Au foils. Predominantly A-A stacked MoS2/WS2and A-B stacked WS2/MoS2are selectively achieved and confirmed. Relative enhancements or reductions in photocatalytic activities of MoS2/WS2or WS2/MoS2are observed under illumination, because the type-II band alignment enables directional electron flow from electrode to active site.
