Highlights •In-situ growth of superlattice structure Cu2S nanoparticles on MoS2 nanosheets has been achieved.•l-cysteineconjugated with sulfur defects on exfoliated MoS2 nanosheets was exhaustively studied.•The intense interfacial effects are formed between Cu2S and MoS2 for 2-Cu2S-MoS2 sample.•2-Cu2S-MoS2 shows enhanced photoreduction efficiency of Cr(VI) and superior stability.•The strategy is extended to successfully construct CdS-MoS2 and ZnS-MoS2 heterojunctions.
