Electrochemical Studies Of Tetrathiafulvalene, 7,7,8,8 Tetracyanoquinodimethane And Their Mixture

Cyclic voltammetry (CV) and Chronoapmerometry (CA) were employed to study the electrochemical oxidation of microcrystalline tetrathiafulvalene (TTF) attached mechanically to the surface of a glassy carbon electrode and immersed in 1 M KBr solution. The effect of temperature, electrolyte concentra...
