Abstract: Electrocatalysis, as a focal point in the fields of nanomaterials and energy chemistry, holds the key to futural energy storage and conversion technologies. Against the backdrop of “carbon peak” and “carbon neutrality”, electrocatalytic nitrate reduction into ammonia is recognized as a green and safe technique. In order to bridge the gap between cutting-edge research and experimental teaching, we have developed a comprehensive chemical experiment centered on electrocatalytic nitrate reduction into ammonia. With an integrated design of basic knowledge, scientific studies and practical applications, this experiment contains hierarchal contents of copper-based catalysts, including its synthesis and characterization, performance exploration and applicable design. This experiment is designed to help undergraduate students gain insights into the latest advancements in electrocatalysis, master its fundamental knowledge and research methods, and foster their innovation awareness and practical application abilities.
