Document Type and Number:
WIPO Patent Application WO/2023/082908
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing hydrogen peroxide by means of catalytic oxygen reduction by using a covalent organic framework catalyst, which belongs to the field of electrocatalysis. According to the present invention, a COF material, which is constructed by using thieno[3,2-b]thiophene-2,5-dicarbaldehyde (DTDA) as a linear construction unit, and respectively using 4,4',4''-(1,3,5-triazine-2,4,6-triyl)triphenylamine (TTT), tris(4-aminophenyl)amine (TAPA) and tris(4-aminophenyl)benzene (TAPB) as center construction units, is used as a catalyst, thereby achieving oxygen reduction preparation of hydrogen peroxide with a high oxygen reducing activity, stability and hydrogen peroxide selectivity. The operation is simple, controllability is high, and a certain universality is achieved.
