Galvanostatic co-electrodeposition of Cu and Pd as Catalyst for Reduction of Nitrates in Water |
| 초록 |
The galvanostatic co-electrodeposition of copper and palladium from 8mM CuCl2 and 5mM PdCl2 in 0.5M HNO3 is studied using cyclic voltammetry and linear sweep voltammetry. The optimized current density for co-electrodeposition is found to beat 7mA/cm2 for 7200 seconds. The prepared electro catalyst showed promising efficiency of reducing nitrates in water at an average of 95-98% reduction from an original 100ppm concentration. This was after applying the optimized reduction current density at 12mA/cm2 for 10800seconds. SEM images reveal the surface deposits to be amorphous and with cauliflower-like structures. This indicates the catalyst as a good alternative for electrocatalys is applications. With added electrolytes, the reduction efficiency of the catalyst was enhanced by 2-3%. Soaking the prepared electrodes in tap water for 14 weeks caused possible detrimental effects on its nitrate reduction efficiency. |
