This invention relates to a dendrite-free zinc electrode for electrochemically mediated amine regeneration, its preparation method, and its application. The invention modifies an electrolyte containing diethylenetriamine, zinc chloride, and potassium chloride using electrolyte additives with carboxyl functional groups (such as sodium maleate, thiosalicylic acid, and ammonium formate). These carboxyl functional groups selectively adsorb onto the zinc electrode surface, enhancing the binding ability of zinc ions to the low surface energy (002) crystal plane of zinc. This guides zinc ions to preferentially deposit along the (002) crystal plane, constructing a flat and dense zinc deposition layer, ultimately effectively inhibiting zinc dendrite growth. A dendrite-free zinc electrode with a high proportion of preferentially oriented Zn (002) crystal planes is prepared by constant current electrodeposition in an electrolyte containing diethylenetriamine, zinc chloride, and potassium chloride. The prepared electrode surface is dense and flat, dendrite-free, with a significantly improved relative texture coefficient of the Zn (002) crystal plane, reduced CO2 desorption energy consumption, and improved corrosion resistance and hydrogen evolution inhibition capabilities. The present invention features a simple process, mild conditions, and low cost, and is suitable for electrochemically mediated amine regeneration carbon capture systems.
