Method for manufacturing disposable gold electrode

The invention discloses a method for manufacturing a disposable gold electrode. The method includes the following steps that firstly, ITO glass serves as a basic electrode, the area of the electrode is fixed, and pretreatment is conducted; secondly, a 3-aminopropyl triethoxy siloxane thin film is manufactured; thirdly, concentration of gold sol is conducted; fourthly, the gold electrode is manufactured. The 3-aminopropyl triethoxy siloxane thin film in the second step is coated with the gold sol in the third step in a dripping mode, the thin film is aired at the room temperature, and therefore the disposable gold electrode can be obtained. According to the method, gold nanoparticles are loaded on the ITO glass electrode, the excellent features of the high specific surface area, the high activity, the high adsorption force, the high catalytic efficiency and the like of the gold nanoparticles are introduced on the surface of the electrode, in addition, due to the fact that the quantity of practical used gold is extremely small, cost is low, and the industrial production of the disposable gold electrode is achieved.
