Method for preparing metal monatomic catalyst through electrochemical deposition

Abstract

The invention is suitable for the technical field of novel materials, and provides a method for preparing a metal monatomic catalyst through electrochemical deposition. According to the invention, metal ions are deposited on alkyne-rich carbon through an electrochemical reduction deposition method, such that the metal monatomic catalyst is obtained. The method comprises the following specific steps: firstly, preparing an alkyne-rich carbon electrode; dissolving soluble metal salt in the electrolyte solution, and adjusting the pH value to obtain an electrochemical deposition solution; and adding the electrochemical deposition liquid by taking the acetylene-rich carbon electrode as a working electrode, a graphite electrode as a counter electrode and a saturated calomel electrode as a reference electrode, and depositing metal ions on the acetylene-rich carbon by adopting an electrodeposition method to obtain the metal monatomic catalyst. The method is simple in process and easy for large-scale production, and has wide application prospects in the fields of catalysis, energy, electronic devices, materials, semiconductors and the like.
