摘要
A study on the performances of mixed hexacyanoferrates of Cu and Pd (CuPdHCFs), potentiodynamically grown on glassy carbon surfaces. was earned out Morphological (SEM-EDX analysis) and electrochemical characterizations were pet formed, and the electrocatalytic ability of films with various compositions was tested by chronoamperometry CuPdHCFs were found to display good electrocatalytic performances. with a maximum sensitivity of 45 3 mA M-1 cm(-2) at 00 V vs SCE (depending on the Cu and Pd ration), against the value of 9 I mA M-1 cm(-2) obtained with pure copper hexacyanoferrate (CuHCF) Additionally, mixed hexacyanoferrates showed a higher pH and operational stability The key role of Cu in Cu-based hexacyanoferrates was investigated and highlighted
