Oxygen reduction reaction RRDE technique

Transition Metal Phthalocyanines Water-soluble tetrasulfonated phthalocyanines incorporating transition metals of the first row, particularly, FeTsPc and CoTsPc, may be regarded as among the first adsorbed macrocycles for which the reaction mechanisms for oxygen reduction in aqueous electrolytes have been studied in depth using RDE and RRDE techniques [60, 90].

Oxygen electro-reduction and evolution reaction/ cyclic voltammetry, rotating ring disc electrode (RRDE) Ni.Al,, Mn204 KOH solution Two preparation methods are used coprecipitation of metal hydroxides and sol-gel route using metal propionates were used. A Teflon-bound electrode technique was chosen with graphite addition The substitution of Al, by Ni increases the catalytic activity. Maximum activity is experienced by NiMn204 Ponce et al. (2001)...
