We incorporated Cu(I) ions into a mesoporous metal–organic framework (MOF) through facile method involving CuCl2 loading, followed by reduction using Na2SO3 as reducing agent. The successful incorporation of Cu(I) ions was supported by various methods such as TEM-EDS, XPS and ICP-AES. Remarkably, the Cu(I) incorporation resulted in 4.2 times higher C3H6/C3H8 selectivity compared with the parent MOF as well as large C3H6 working capacity (1.3 mmol/g) at 10–100 kPa. Moreover, the Cu(I)-loaded MOF showed efficient separation of C3H6 from C3H8 under dynamic mixture flow conditions, easy regeneration under mild conditions, and good stability under atmospheric conditions.
