摘要：

In this work, g-C3N4 nanotubes (CNtb) with sheet-like graphdiyne (GDY) composite are successfully prepared through a simple self-assembly method. The composite is proved to significantly improve the separation efficiency of photogenerated carriers and the conductivity of the material, which consequently leads to enhanced performance towards photocatalytic CO2 reduction. For the composite, the yields for CO and CH4 are increased by 18-20 times, compared with pure CNtb. This work provides a new idea for the preparation of efficient g-C3N4 photocatalysts in the future.
