Problems solved by technology

OER exhibits slow kinetics and simultaneously induces changes in the structure of electrode materials, leading to large differences in electrode performance
Currently, ruthenium (Ru) and iridium (Ir) oxides have proven to be the best OER catalysts, but they are scarce metal oxides, and their high cost and rapid deactivation severely hinder their use.

Embodiment Construction

[0035] The following examples further illustrate the present invention, but are not limited thereto.

[0036] 1. Preparation of Hydrangea-shaped CuZnO X nanomaterials:

[0037] (1) Weigh 2.195g of Zn(CH 3 COO) 2 , dissolved in 50mL of deionized water to obtain 50mL of zinc salt solution.

[0038] (2) Weigh 1.642g of 2-methylimidazole and dissolve in 60mL of deionized water to form 60mL of organic ligand aqueous solution.

[0039] (3) Weigh 1.25g of CuSO 4 • 5H 2 O was dissolved in 10 mL of deionized water to form 10 mL of copper sulfate aqueous solution.

[0040] (4) Quickly add the zinc salt aqueous solution to the organic ligand aqueous solution obtained in step (2), and stir at room temperature for 24 hours to obtain an intermediate product, wash with water and ethanol, and dry naturally to obtain 1.58g zinc metal zeolite imidazole skeleton material.

Abstract

The invention relates to a preparation method of a hydrangea-shaped CuZnOX nanometer material and application of the hydrangea-shaped CuZnOX nanometer material to electrocatalysis, and belongs to thetechnical field of nanometer material preparation. After a zinc salt water solution and an organic ligand water solution are mixed, stirring reaction is performed under room temperature condition; anobtained zinc metal zeolite imidazole type framework material and a copper sulfate water solution are mixed again; under room temperature condition, stirring reaction is performed till the reaction isfinished; water and ethyl alcohol are used for cleaning; a zinc-copper metal organic framework material is obtained; through calcination, the hydrangea-shaped CuZnOX nanometer material is obtained. The operation is simple; the used raw materials are nontoxic; the environment is protected; the cost is low; the process is simple; the operation and the control are easy; the preparation method is suitable for continuous large-scale production; no pollution exists in the preparation process; the safety is high.

Description

technical field [0001] The invention belongs to the technical field of preparation of nanomaterials, in particular to hydrangea-shaped CuZnO X Preparation methods of nanomaterials. Background technique [0002] Due to the harmful gas CO 2 Increasing concentrations are motivating more researchers to seek cleaner renewable energy sources to replace fossil fuels. As a carbon-free energy carrier, H 2 It has been welcomed by researchers as an ideal alternative due to its high conversion efficiency. So far, water electrolysis has been considered to produce H 2 The main and simplest method, but the efficiency is still limited, mainly due to the property of anodic oxidation, namely the oxygen evolution reaction (OER). OER exhibits slow kinetics and simultaneously induces structural changes in electrode materials, leading to large differences in electrode performance. Currently, ruthenium (Ru) and iridium (Ir) oxides have proven to be the best OER catalysts, but they are scarce...
