Size Dependent Electrocatalysis of Gold Nanoparticles

A Microscopic View on the Electrochemical Deposition and Dissolution of AU with Scanning Electrochemical Cell Microscopy – Part Ii: Potentiostatic Dissolution and Correlation with In-Situ Ec-Tem

“…Gold is a noble metal with good conductivity and stability, making it a material of interest for many applications, including sensors, electrocatalysis, and as a working or counter electrode in conventional electrochemical studies. [1][2][3][4] However, in acidic electrolytes, the properties of gold are affected during electrochemical oxidation and reduction of the gold surface. [5][6][7] In addition, gold undergoes anodic dissolution in the presence of complexing agents such as Cl -, Br -, or CN -, which modifies the surface structure and affects its properties.…”
