The invention discloses a preparation method of a carbon nitride (CN) electrode material. The preparation method comprises the following steps: (1) preparing a precursor film: immersing a clean conductive substrate A into a hot saturated CN precursor aqueous solution, then immediately taking out, after the surface being dried, a uniform precursor film layer on the conductive substrate A was formed. This step can be repeated several times to get different layers of precursor film on the substrate A; (2) preparing the CN electrode: the dry precursor film obtained in step (1) was encapsulated in a glass tube filled with N. Then the glass tube was inserted into a furnace with Natmosphere to calcinate. After calcination, the uniform CN film electrode was obtained. The method provided by the invention is simple and easy to implement, and convenient in used equipment, suitable for industrial application and popularization.
