Pd nanoparticles-embedded RGO for superior catalytic activity towards 4-nitrophenol reduction and highly sensitive electrochemical 4-nitrophenol pollutant |
| 초록 |
We illustrate a facile approach for in situ synthesis of Pd-gum arabic/reduced graphene oxide (Pd-GA/RGO) using GA as the reducing agent, which favors the instantaneous reduction of both Pd ions and GO into Pd nanoparticles (NPs) and RGO. The catalytic reduction of 4-NP was highly pronounced for Pd-GA/RGO (5 min) when compared to Pd NPs (140 min) and Pd/RGO (36 min). This enhanced catalytic activity was attributed to the synergistic effect of Pd NPs and the presence of various functional groups of GA. Significantly, the fabricated sensor offered a low detection limit (9 fM) with a wider linear range (2-80 pM) and long-term stability. The results indicated that the as-prepared Pd-GA/RGO exhibited better sensing ability than the other graphene-based modified electrodes. Therefore, the proposed sensor can be employed as a more convenient sensing platform for environmental and industrial pollutants. |
