Synthesis of Carbon Dots from Rice Straw and Its Application to Produce Efficient Electrocatalysts for Hydrogen Evolution Reaction |
| 초록 |
We report a facile method to synthesize carbon dots (Cdots) from rice straw and then use it as a directly reducing agent as well as a stabilizer to produce Cdots@Au nanoparticles. Rice straw-derived Cdots possesses oxygenated groups, which act as an electron-donating source to reduce Au3+ to Au0. The strong Au-carbon interaction propels a high electron transfer for Cdots@Au electrocatalyst towards enhanced-performance in hydrogen evolution reaction (HER). When Cdots@Au electrocatalyst is used for the HER process, the HER activity is maintained stable for 2000 cycles. The overpotential is 150 mV at a current density of 10 mA.cm-2, which is the outstanding HER performance for Au nanoparticles as a non-Pt HER electrocatalyst. |
