Abstract

The invention discloses a method for spontaneously growing Au nanometer particles on an electro-deposited CdSe film. Mixed solution of divalent cadmium salt and selenium dioxide (SeO2) is used; firstly, CdSe is deposited on the surface of an electrode by using an electro-deposition method to form a carrier film; the electrode is dipped in Au nanometer particle growth liquid for growing by 1-3 hours in a constant-temperature water bath boiler; and finally, the electrode is taken out to spontaneously grow the Au nanometer particles. The method is simple in preparation steps; and the deposited composite film is strong in adhesive force, high in efficiency, low in cost and more suitable for large-scale production.

Description

technical field

[0001] The invention belongs to the field of nanometer materials and electrochemistry, and in particular relates to a method for spontaneously growing Au nanoparticles on electrodeposited CdSe thin films. Background technique

[0002] Cadmium selenide (CdSe) is an n-type semiconductor material with a direct energy gap. Its forbidden band width is about 1.8eV. It is a semiconductor material with relatively stable chemical properties. It has unique photoelectric conversion characteristics and is often used to improve the wide band gap. Semiconductors have attracted much attention in order to improve their ability to absorb visible light and photocatalytic activity in photocatalytic oxidation technology for environmental pollution control and photocatalytic (PEC) water splitting, but it has an obvious shortcoming, photogenerated electrons Combining with holes will make the photocatalytic activity not high, so the activity of the catalyst must be improved, the mo...
