Flowerlike MoS 2 microspheres were synthesized through a hydrothermal method. 2H‐MoS 2 nanoparticles, MoS 2 /MoO 3 heterojunctions, and α‐MoO 3 nanoplates were prepared by annealing the MoS 2 microspheres under different reaction conditions. The formation and growth mechanism of the samples from flowerlike MoS 2 microspheres to α‐MoO 3 nanoplates is explained in detail. The photocatalytic properties of the four samples for the degradation of rhodamine B (RhB) under visible‐light irradiation were studied. The results showed that the flowerlike MoS 2 microspheres, MoS 2 /α‐MoO 3 heterojunctions, and α‐MoO 3 nanoplates all have excellent photocatalytic activities. In particular, the flowerlike MoS 2 microspheres exhibit the highest photocatalytic activity for the degradation of RhB.
