Document Type and Number:
WIPO Patent Application WO/2023/219091
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an ammonia separation membrane having a composition that is different from those of conventional ammonia separation membranes; and a method for separating ammonia using this ammonia separation membrane. The present invention provides an ammonia separation membrane which is characterized by comprising a metal cyano complex represented by formula (1) and an oxide porous body wherein pores have no specific shape. (1): AxM1[M2(CN)w]y∙zH2O
(In the formula, each of M1 and M2 represents a metal atom such as a vanadium atom; A represents an atom such as a hydrogen atom; x represents a number of 0 to 4; y represents a number of 0.1 to 2; z represents a number of 0 to 6; and w represents a number of 4 to 8.)
