Abstract :
This paper presents pulse potential electrodeposition of platinum nanoparticles on fluorine doped tin oxide (FTO) from AlCl3-NaCl molten salt containing K2PtCl6 at 393K. The results showed that by optimizing the deposition parameters including the on potential, off potential, on time and duty cycle we are able to improved catalytic performance of PtNPs/FTO modified electrode for ethanol electrooxidation. The two- level factorial design was used to screen and optimize the pulse potential electrodeposition variables. The prepared PtNPs/FTO electrodes were characterized by scanning electron microscopy, Energy-dispersive X-ray spectroscopy and cyclic voltammetry. The prepared PtNPs/FTO exhibited high performance in the electrocatalytic oxidation of ethanol in alkaline solution
