英文摘要 | The electrode of multi-walled carbon nanotubes was treated by a dual-stepped surface thiolation process. The carbonate ligands were landed at the surface of MWCNTs by nitric acidifies. Thiol groups were conjugated at the CNT-COO- end in the second step. The obtained MWCNTs electrode contains significantly improved Pt nanoparticles dispersion and methanol electrooxidation activities (improved by 350%) comparing to that treated by acidifies reactions. |
