Can Pt wire be dissolved under CV test during 0 to -0.6 V(Ag/AgCl) in 0.5 M H2SO4?
After 1000 cycles CV test, I find there are Pt nanoparticles on the working electrode. Are the Pt nanoparticles from the dissolvation of Pt wire, then electrolytic deposition on the working electrode?
reference electrode: Ag/AgCl, counter eletrode: Pt wire, working eletrode: Glassy Carbon Electrode, electrolyte: 0.5M H2SO4. under air atmosphere.
