Gold disk electrode is one of the most widely used working electrodes. Unlike platinum, gold does not produce proton adsorption and desorption waves, and the overpotential of proton reduction and hydrogen evolution is greater than that of platinum, so the potential window in the reduction region of the aqueous solution Wider than platinum. The surface of gold is easy to be chemically modified and modified with thiol compounds, and it is used in many research fields according to research purposes.

There are four types of insulating rods for gold disc electrode jackets.

Gold disc electrodes are divided into straight type, L type, T type and detachable type. The material surface of the straight gold disc electrode is vertically downward. The detachable gold disc electrode is connected by a 7mm length electrode head and electrode rod through a thread. A separate electrode head can be used for scanning electron microscopy and other tests.

Application note:
The disk electrode is immersed in the ion-conducting solution as a working electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the experiment, the electrode should be washed several times with ethanol. If the disk electrode was used as a current collector with other electrode material, or when there are visible traces of material absorption, it should be polished down to the mirror surface after the experiment is completed. Store the working disk electrode in the glass tube sealed with an O-Ring (all included in the package). An instruction on maintenance is provided in Electrode Polishing Kit product page.
