Title:
LEAD NANOSHEET-GRAPHENE TWO-DIMENSIONAL COMPOSITE, PREPARATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/068491
Kind Code:
A1
Abstract:
The invention relates to the technical field of catalysts for carbon dioxide electrocatalytic reduction, in particular relating to a preparation method of a lead nanosheet-graphene two-dimensional composite. The method comprises the following steps: weighing 10 mg of graphene oxide according to a certain ratio and adding the same to a 10 mL beaker; adding 5 mL of a solution of 0.05 mol/L Pb(NO3)2 to the beaker and leaving to soak at room temperature; after the soaking is complete, centrifuging to remove a metal solution, followed by adding 10 mL of a solution of 0.01 g/mL NaBH4 and causing same to react at room temperature to obtain a mixed product; after the reaction is complete, centrifuging and washing the mixed product using deionized water; adding 1 mL of water to the obtained product, uniformly dispersing same using ultrasonic dispersion, and obtaining a lead nanosheet-graphene two-dimensional composite dispersion liquid. In the present invention, an inexpensive and simple preparation method for preparing a lead nanosheet-graphene two-dimensional composite is provided. Also provided is an application of a high-performance lead nanosheet-graphene two-dimensional composite in carbon dioxide electrocatalytic reduction.
