Effect of pH to the Morphology of Co3O4/rGO and Sensitivity of Composite with H2O2 |
| 초록 |
Co3O4 is one of the most promising candidates among the transition metal oxide. As Co3O4 has specific capacity (more than 1000 mAhg-1), many researches have been done on supercapacitors. Co3O4 is a p-type semiconductor with electrical conductivity highly sensitive and also has applications in sensor area. The research goal for sensors is to get a high surface area. In this work, we synthesized Co3O4/rGO (reduced graphene oxide) by simple hydrothermal method. The effect of pH on the morphology of final product is investigated in detail by XRD (X-ray diffraction), SEM (scanning electron microscopy, TEM (transmission electron microscopy), and FT-IR (Fourier transform infrared spectroscopy). The different sensitivityto H2O2 is checked by CV (cyclic voltammogram). |
