▎ 摘　　要

2D materials-based heterostructure has an abundant charge transport channel and shortened charge transport distance, which can realize the effective transfer and separation of photo-generated carriers. Herein, heterostructures of MoS2/graphene are fabricated for photocatalytic degradation under natural light. An excellent performance of methylene blue (MB) photodegradation is found, which surpassed the ability of the monomer materials of 2D MoS2 and graphene. Furthermore, the optimal mass ratio of the precursors and the micromorphology of the as-constructed heterostructures are also confirmed.
