چکیده
Design and application of powder composite electrodes for electrosynthesis and electroanalysis research has been carried out. The physical characterization of electrodes was analysis using SEM, EDX and FTIR. The electrochemical stability was analysis using cyclic voltammetry. The stability of electrodes was analyzed using Atomic Absorption Spectroscopy (AAS). The powder composite electrodes were prepared by mixing 95% metal powder with 5% polyvinyl chloride (PVC). PVC was used as a binder and tetrahydrofuran (THF) was used as a mixing solvent in powder composite electrodes preparation. The result, of the study showed powder composite electrode higher stability compared to metal sheet electrode. Electrooxidation of ethanol in KOH solution powder composite electrodes has shown good stability based on analysis using AAS. The composite electrode has shown higher current density, so that we use for electrochemistry research such electrosynthesis, electroanalysis and electrodegradations.
