Modification of commercial Pt/C catalyst by cobalt for enhanced electro-oxidation of ethanol

Optimized Electrodeposition of Ni2O3 on Carbon Paper for Enhanced Electrocatalytic Oxidation of Ethanol

“…The third part (III) is characterized by an irregular semicircle, representing the electrical response of the double-layer capacitance on the surface of the working electrode, the charge transfer resistance, and the reaction-related diffusion or mass transfer impedance. These are denoted by CPE, R ct , and W s , respectively . The fourth part (IV) at the low-frequency region shows a straight line-like portion, resulting from the combined effect of the apparent inductance affected by the adsorption of reactants on the surface of the electrode and the diffusion or mass transfer impedance associated with the reaction.…”
