Title:
HIGH-ENTROPY ALLOY ELECTRODE AND PREPARATION METHOD THEREFOR, GAS SENSOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/016268
Kind Code:
A1
Abstract:
Provided in the present application are a high-entropy alloy electrode and a preparation method therefor, which preparation method comprises: dissolving a soluble metal salt, a complexing agent, an antioxidant and an acidic standard volumetric solution in an aqueous solution to obtain an electroplating solution; and subjecting a conductive substrate to electrochemical deposition in the electroplating solution to obtain a high-entropy alloy electrode. The preparation method for a high-entropy alloy electrode provided in the present application can be carried out at room temperature or at a temperature slightly higher than room temperature and realize uniform deposition on various different substrates due to the use of an electrochemical deposition method, and the operation is easy and the cost is low; and by controlling factors such as the pH, deposition time and temperature, the morphology of the surface of a film and the content of a metal element is made to be different so as to adapt to different application scenarios. In addition, further provided in the present application are the use of the high-entropy alloy electrode and a gas sensor comprising the high-entropy alloy electrode.
