Embodiment Construction

[0035] 1. Preparation process steps:

[0036] (1) Add 50mL of 0.1M copper acetate solution dropwise into 50mL of 0.1M oxalic acid solution, and stir magnetically for 1 hour until the system completely turns into a blue precipitate.

[0037] (2) The blue precipitate was washed three times with deionized water and absolute ethanol, and then dried in an oven at 60°C.

[0038] (3) The dried samples were taken out from the oven and washed with deionized water and absolute ethanol three times, then dried in an oven at 60°C, and then calcined in a tube furnace.

[0039] Calcination conditions: in an air atmosphere, the temperature was raised to 350°C at a rate of 1°C per minute, then kept for 2 hours, and naturally cooled to room temperature to obtain a sample of copper oxide electrode material S1 with a porous nanostructure.

[0040] Parallel test 1: in the air atmosphere, the temperature was raised to 450° C. at a rate of 1° C. per minute, then kept for 2 hours, and naturally cool...

Abstract

The invention discloses a copper oxide electrode material of a nano-porous structure and a preparation method and application thereof, and belongs to the technical field of new energy and electrochemical sensor electrodes. The method comprises the steps of dropwise adding a copper acetate water solution into an oxalic acid water solution and reacting under a magnetic stirring condition; and carrying out cleaning and drying treatment by using deionized water and absolute ethyl alcohol and then burning to obtain the copper oxide electrode material of the nano-porous structure. The material is of a porous cystic three-dimensional structure, the front surface is a square, the edge is in a flat form, the middle is convex, and the side surface is in a spindle form. The material is dispersed into a nafion solution and coats a glassy carbon electrode which is polished through Al2O3 turbid liquid and treated through a sonic degradation method to obtain the electrochemical sensor electrode. Electron transfer reaction can be promoted, good electrochemical activity is provided, electron transmission is facilitated, and the copper oxide electrode material has potential application values.
