Amorphous Ni-Mn oxide electrodeposited on activated carbon for capacitive deionization |
| 초록 |
Pseudocapacitive materials are very promising electrodes for capacitive deionization since they have the ability to have high electrosorption capacity and rate. Manganese and its oxides have been used extensively due to its high theoretical capacitance, low cost and environmental friendliness. Studies has shown that mixing in Ni with Mn can improve its conductivity as well as tune its morphology. In this study, an amorphous Ni-Mn oxide was coated on activated carbon through anodic electrodeposition at constant current. Its deposition on activated carbon improved its wettability and showed an improvement in specific capacitance and charge transfer resistance. CDI testing revealed that Ni-Mn oxide as the cathode yielded higher electrosorption capacity, charge efficiency and stability than a symmetric cell of activated carbon. This shows that Ni-Mn oxide has a great potential for CDI and its easy fabrication can pave the way for commercialization and/or a large-scale application. |
