Abstract
1 min read
A growth-temperature-mediated two-step chemical vapor deposition strategy is designed to synthesize MoS<sub>2</sub> /WS<sub>2</sub> and WS<sub>2</sub> /MoS<sub>2</sub> stacks on Au foils. Predominantly A-A stacked MoS<sub>2</sub> /WS<sub>2</sub> and A-B stacked WS<sub>2</sub> /MoS<sub>2</sub> are selectively achieved and confirmed. Relative enhancements or reductions in photocatalytic activities of MoS<sub>2</sub> /WS<sub>2</sub> or WS<sub>2</sub> /MoS<sub>2</sub> are observed under illumination, because the type-II band alignment enables directional electron flow from electrode to active site.
