摘要
A method for forming a hybrid zeolitic imidazolate framework (ZIF) comprises the formation steps of: preparing a first solution comprising: a 2-methylimidazolate or a functionalized derivative thereof; and a carboxaldehyde-2-imidazolate or a functionalized derivative thereof; preparing a second solution comprising a metal ion; and combining the first solution and the second solution to form the hybrid ZIF, wherein a first fraction of 2-methylimidazolate or a functionalized derivative thereof in the hybrid ZIF is from about 5 to about 95 or any value there between and a second fraction carboxaldehyde-2-imidazolate or a functionalized derivative thereof in the hybrid ZIF is 100—the first fraction is disclosed. A metal-organic framework (MOF) comprising the hybrid ZIF and a molecular sieve device comprising the hybrid ZIF are also disclosed.
