摘要
1D/2D Co 3 O 4 /ZnIn 2 S 4 core-shell heterostructure with excellent hydrogen production properties under visible light irradiation • 1D/2D hierarchical Co 3 O 4 /ZnIn 2 S 4 heterojunction was successfully fabricated. • Co 3 O 4 /ZnIn 2 S 4 displays dramatically ascendant photocatalytic hydrogen evolution performance. • The photocatalyst shows a long-term stability of photocatalytic hydrogen evolution for cumulative 20 h. • The enhanced interfacial charge separation and migration induced by the generated robust built-in electric field. Multidimensional hierarchical hollow Co 3 O 4 /ZnIn 2 S 4 tubular core–shell heterostructures were prepared by growing ultrathin two-dimensional ZnIn 2 S 4 nanosheets on one-dimensional hollow Co 3 O 4 nanotubes by a simple solvothermal method. The design of this multidimensional hollow core–shell heterostructure not only avoids the self-assembly aggregation of ZnIn 2 S 4 nanosheets but also broadens their light-absorption range and improves the utilization of visible light. The internal electric field formed by the p–n heterojunction in the photocatalyst can promote the separation and migration of photogenerated e − and h + species, and therefore the recombination of photogenerated carriers can be effectively suppressed.
