“…where 0.4463 is Randles-Sevcik constant, n is the number of electrons, F is the Faraday constant (96500 C mol À1 ), A is the electrode surface area (cm 2 ) [15], C is the concentration of the electroactive species (mol cm À3 ), v is the scan rate (V s À1 ), and D is the diffusion coefficient (cm 2 s À1 ). The obtained diffusion coefficient (D) for RLTP was 5.94 Â 10 À15 cm 2 s À1 , which is fairly close to previously reported value [4].…”
