The present invention belongs to the technical field of electrode preparation, and discloses a preparation method of an anti-scaling electrode with automatic scale shedding, and the steps are as follows: pretreatment of the substrate, construction of active sites, coating of an inert surface, and strengthening of active sites. Different from the traditional method of cleaning the cathode after scaling, the present invention takes a new approach and constructs a highly dispersed nano-tip active site on the inert surface to achieve the positioning and directional growth of scale on the electrode. The hydrogen bubbles generated by electrolysis on the active sites will transfer along the inert surface and coalesce into a bubble layer and large bubbles, thereby preventing the surface from undergoing the electrolysis and scale nucleation processes. Therefore, only the top of the nano-tip serves as the reaction site for electrolyzing water and the landing point for scale crystals. As the scale grows, the nano-scale foothold is difficult to support, and finally it spontaneously falls off under the vibration generated by the bubble rupture. The present invention opens a window for solving the problem of cathode scaling and has scientific value and practicality for the application of electrochemical technology in actual water bodies.
