摘要	Rotating Disk Electrode (RDE) electrochemistry combined with Koutecky-Levich analysis is a powerful electrochemical technique that decouples diffusion-limited and kinetically limited electron-transfer processes. Developed by Levich in the 1960s, RDE enables determination of heterogeneous electron-transfer rate constants and mechanistic information by rotating an electrode to control mass transport.	Chronoamperometry (CA) is an electrochemical technique that measures current as a function of time when a potential step is applied to an electrode. Developed by Delahay in the 1950s, CA reveals diffusion-controlled electrochemical processes and enables determination of diffusion coefficients, surface coverage, and kinetic rate constants by analyzing the transient current decay.	Cyclic Voltammetry (CV) is an electrochemical technique that measures redox reactions by varying the voltage applied to an electrode and monitoring the resulting current. Developed by Nicholson and Shain in 1964, CV is one of the most widely used electrochemical methods, providing rapid information about the redox potentials and electron-transfer kinetics of molecules and materials.
