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