Document Type and Number:
WIPO Patent Application WO/2022/215808
Kind Code:
A1
Abstract:
The present invention relates to a novel supramolecular self-assembly, a carbon nitride and a photocatalyst using same, and a manufacturing method therefor. The present invention can provide, by using a supermolecular self-assembly, a carbon nitride having a high N-C=N bonding ratio, a photocatalyst having excellent photocatalytic activity under visible light, and a manufacturing method therefor, the supermolecular self-assembly comprising: a plurality of complex units formed by hydrogen bonding two or more nitrogen-containing compounds to each other; and linker units connecting the plurality of complex units by hydrogen bonds, wherein the nitrogen-containing compounds and the linker units are each independently a –NH group and capable of hydrogen bonding with the -NH group, and the supermolecular self-assembly contains one or more heteroatoms selected from the group consisting of N, S, and O.
