| Abstract: |
| Objective Preparation of Cu/Cu2O hybrids and its control of morphology in only one-step. Methods Crystal morphology and copper content of the sample have tuned by changing the reaction time, temperature, usage amount of raw material, the proportion of the mixed solution. Results The copper content in the Cu/Cu2O hybrids increased significantly with the increasing of the usage amount of ammonia and formic acid, but decreased with the increasing of the usage amount of copper nitrate and the content of water in the mixed solution. However, no obvious vary in the copper content of Cu/Cu2O hybrids with the changes of reaction temperature and time. Moreover, the morphology of the sample changed from cauliflower shape, six-foot shape, regular octahedron, dodecahedron to globular with the increasing of the usage amount of ammonia and formic acid, but he changes of morphology is opposite with the increasing of the usage amount of copper nitrate and the content of water in the mixed solution. In addition, the morphology of crystal change to regular octahedron and pore began to emerge with the increasing of the reaction temperature. Conclusion Cu content in the Cu/Cu2O hybrids and morphology can successfully regulated by changing the synthesis parameters. |
