Abstract: Heterostructure nanoparticles have excellent photoelectrochemical properties, because of the difference of heterostructure characteristics will greatly affect the performance of the play. Therefore, the selective growth of heterostructure nanoparticles is an important research content in the design and synthesis of advanced materials. In this thesis, the octahedral Cu2O crystal was used as the research object. By adjusting the reaction time and the kind and quantity of Surfactant, the nucleation and growth mode of Cu nanoparticles can be different. So that, Cu nanocrystals can be grown in situ at different positions such as the edges and faces of the octahedral Cu2O, and the Cu2O-Cu heterostructures with different spatial configurations were precisely constructed. The results showed that the content of Cu particles on the Cu2O surface also increased with the increase of reaction time. The addition of surfactant PVP hinders the in-situ growth of Cu nanoparticles on the Cu2O surface edge. The addition of CTAB can increase the particle size of Cu nanoparticles. And the addition of SDS can reduce the particle size of Cu nanoparticles while preferentially growing and aggregating on the octahedral Cu2O edge.
