Preparation of CdIn2S4 nanoparticles@MoS2 microrods heterojunctions for boosted photocatalytic hydrogen production

Novel CdIn2S4 nanoparticles@MoS2 microrods (CNPs@MMRs) heterojunction photocatalysts were synthesized via a facile solvothermal method. The photocatalytic properties of CNPs@MMRs composites for H2 generation were more prominent than those of the pure CdIn2S4 and MoS2. Among, CNPs@MMRs-40 exhibited the maximum H2 evolution efficiency of 539 μmol g−1 h−1. Moreover, CNPs@MMRs-40 possessed excellent photochemical stability during 4 cycles of photocatalytic reactions. CdIn2S4 nanoparticles were intimately decorated on the surface of MoS2 microrods, which strengthened the absorption of visible light, facilitated the migration and separation of charge carriers. Consequently, photocatalytic efficiency of CNPs@MMRs composite was dramatically enhanced.
