The significant surface charge rearrangement and abundant surface active sites generated by the construction of chain heterojunction are conducive to greatly improving the ZnO catalytic performance ( Fig. 9 e).
The chain-like structure of ZnO/ZnS heterojunction was successfully synthesized through electrospinning and ion exchange methods. It is verified that the structure of ZnO/ZnS heterojunction is helpful to promote carrier transport at the interface and realize effective charge transfer.
Combined with DFT theoretical calculation, through in-depth analysis of the interface structure change and charge transport performance, the electronic structure of heterojunction structure promotes the separation of photo-generated carriers and the charge transfer, and the corresponding performance of hydrogen production is also greatly improved.
Compared with bare ZnO, the chain-like ZnO/ZnS heterojunction shows better photocatalytic hydrogen production performance. When the Na 2 S concentration was 0.064 M, the hydrogen production of ZnO/ZnS exhibits the best performance (1140.64 μmol. g −1 ).
Therefore, by introducing the heterojunction array structure, the carrier separation channel is increased by the interface area of the heterojunction, thereby improving the carrier separation and collection efficiency.
In recent years, metal compound-based heterojunctions have received increasing attention from researchers as a candidate anode for lithium/sodium-ion batteries, because heterojunction anodes possess unique interfaces, robust architectures, and synergistic effects, thus promoting Li/Na ions storage and accelerating ions/electrons transport.
